It draws on empirical research conducted on the under researched security network for art in the capital. In light of ‘new policing’ theses (McLaughlin 2007), the article investigates how the theory of nodal governance (Johnston and Shearing, 2003) can operate in an actual policing arena. With other government nodes and private stakeholders producing much of the art security, this article argues that a nodal governance framework is beneficial to the public police as it allows them to take an important role in the policing when they are best suited to doing so, and a lesser role in other areas when and where other nodes have greater capacity.

Isleworth Mona Lisa (Wiki)

'La Joconde' (1503-1506) has mostly hung in the Louvre (INV. 779) since Francois I acquired it in 1518.  Last week The Mona Lisa Foundation reintroduced the 'Isleworth Mona Lisa' which had not been seen in public for more than 40 years and declared that it was an earlier unfinished portrait of Lisa Gherardini del Giocondo by da Vinci.

Jamie Keaton for the Associated Press (published online here in Business Week) reported on the unveiling of the Isleworth Mona Lisa in Geneva on September 28.  Keaton points out the Alessandro Vezzosi (see below) 'declined to line up behind the foundation's claim that it was truly a "Mona Lisa" predecessor painted by da Vinci.  Here, on the Museo Ideale Leonardo da Vinci's website, Professor Vezzosi clarifies that research on  the "Isleworth Mona Lisa" will continue.

The Mona Lisa Foundation, a non-profit organization based in Zurich, has on its website a 22-minute video that walks the viewer through its claim, using historical documentation (including writings of 16th century art historian Giorgio Vasari), connoisseurship, critical comparisons and physical and scientific examinations.  Participants in the video include Professor Alessandro Vezzosi, Director of the Museo Ideale Leonardo da Vinci; Professor John F. Asmus, Research Physicist at the University of California in San Diego; Stanley B. Feldman, and art historian and principal author of "Mona Lisa - Leonardo's Earlier Version".  The video asks if it is possible that there was another Mona Lisa and if so, what could have happened to it? It is claimed that Giorgio Vasari and Agostino Vespucci mention a painting left unfinished.  In the early 20th century, Hugh Blaker, curator of The Holburne Museum  in Bath, believed in the two Mona Lisa painting theory and spent a decade looking for the unfinished version until he found it "in the Somerset home of an English nobleman" "who's family had owned the painting for nearly 150 years."  Blaker brought it to his London studio in Isleworth, then shipped it to the United States where it hung in the private offices of the Boston Museum of Fine Arts, according to the video.  Then in 1922, Blaker sent the Isleworth Mona Lisa to Italy for the opinion of experts there.  In 1926, Baker's stepfather, John Eyre, published "The Two Mona Lisas."  Henry F. Pulitzer, over a period of 26 years, liquidated his Kensington estate and part of his art collection to purchase the Isleworth Mona Lisa.  In 1979, after Pulitzer's death, the painting was locked up in a Swiss Bank vault "where it would remain for more than four decades."  "Can science at least succeed where connoisseurship has failed [in establishing the painting's authenticity]?" In 2004, the Isleworth Mona Lisa was removed from its security vault and "entrusted to world renowned art auctioneer David Feldman" (Vice President of the Mona Lisa Foundation).  "Over the next 12 years, the painting went through every test" including examination by Professor Asmus who has also examined the Louvre Mona Lisa who saying "Leonardo's hand" is evident in some aspects of the Isleworth Mona Lisa.

But there are more potent reasons to attach the greatest importance to the new discovery.  There is, in the collection of old master drawings at the Louvre an original pen drawing by Raphael, which is reproduced in Muntz's great work on Leonardo, and which is generally admitted to be a memory sketch by Raphael of Leonardo's "Mona Lisa."  Now this memory sketch is framed at both sides by two columns of which no trace is to be found in the Paris "Mona Lisa." These columns appear in the identical place in the Isleworth picture and are of immense value to the harmonious balance of the composition. 

In the notice sent out to the press it is stated that these columns are mentioned by Vasari, which is as little in accordance with facts as most of the other statements made.  Thus, one of the points quoted in favor of the authenticity of the picture is one of Leonardo's letters to Marshal de Chaumont.  In this letter occurs the passage: "E portar con mecho due quadri di due Notro Donne di varie grandezze le qual son fatte pel cristianissimo notro re."  While most art historians have misread this to mean that Leonardo took with him "two pictures of Our Lady, of different sizes," the writer of the widely circulated notice says that the existence of two versions of the "Mona Lisa" is proved by Leonardo himself referring to two portraits.  A literal translation of the quoted passage would however run as follows: "And take with me two portraits of two of our ladies, of different sizes, which have been painted for our most Christian King", the letter thus reflecting clearly to two different ladies and not to two versions of the same. 

However, no specious arguments are needed for the Isleworth picture, the quality of which may speak for itself.  And a close investigation of the picture leaves the firm conviction that, though not altogether from the hand of Leonardo da Vinci himself, it emanates most certainly from his studio and was very largely worked up by the master himself.  The hands, with their careful and somewhat hard drawing and terra cotta coloring, suggest at once the name of Leonardo's pupil, Marco d'Oggionno, whereas the inimitably soft and lovely painting of the head and bust, the exquisite subtlety of the expression, the golden glow of the general coloring, can be due only to Leonardo.  The face shows none of the defects of the Louvre picture, which are probably due to clumsy repainting. 

The present owner of the picture acquired his treasure only about a year ago.  He found it hidden in a Somerset mansion where it had been for a century and a half, and whither it had been brought from Italy.

The oil on canvas, believed to be worth more than £2 million, was recovered during a special police operation in Croydon High Street on Monday last week. A man in his sixties was arrested and taken to Croydon Police Station. Scotland Yard said the arrest was part of an ongoing Proceeds of Crime Act investigation by officers from the Met's specialist crime directorate. Detectives refused to comment on whether a painting by Dutch master Rembrandt Harmenszoon van Rijn was among the items seized during the operation. But a source told the Advertiser: "The way the officers were handling the painting and keeping it safe, they clearly believed it was a Rembrandt." It is understood the painting has been sent away to experts to be authenticated. The arrested businessman, who cannot be identified for legal reasons, lives in Surrey.

Police were seen treating the potentially precious object with extreme caution as they removed the work from the building in south London following the raid on Monday June 11. Now experts have been called in to examine the work of art to establish if the work recovered, really is a Rembrandt masterpiece. Scotland Yard, who are being tight-lipped about which one of the 205 currently missing works by the Dutch master, also arrested a businessman in his sixties. Detectives from the Metropolitan Police's specialist crime directorate made the discovery during a long-running investigation aimed at recovering assets from criminals.

Security expert Richard Ellis, who has worked with the Met Police's specialist Art and Antiques squad, said: 'If this is a genuine Rembrandt oil painting, I think £2million would be a massive undervaluation. 

'If you were to put one before an auction today it would fetch between £30million and £50million. 

Mr Ellis, who last year was part of the team which recovered two paintings by Pablo Picasso stolen from a Swiss exhibition in 2008 in Belgrade, Serbia, added: 'To sell a real Rembrandt on the open market would be really, really difficult. 

'Any buyer undertaking their due diligence would look at the catalogues of Rembrandts and it wouldn't take them very long to see it was stolen.' 

'Stealing to order is fiction. They may get stolen and used as a form of currency or as collateral. 

'The media would publish the valuation at the time of the theft and the criminal would work on the basis that it would be worth to them anywhere between three and ten per cent, because that's what it can get passed across on the black market. 

'It acts as a sort of international currency.'

A REMBRANDT masterpiece seized in Croydon was a fake, the Advertiser can reveal. Businessman Shaun Stopford-Claremont, 62, was arrested in possession of the painting during a special police operation in Croydon High Street in June. The painting was then sent to top art experts to be authenticated. If a genuine work of the Dutch master it could have been worth as much as £50 million. But this week Scotland Yard confirmed to the Advertiser the painting is a forgery. Mr Stopford-Claremont, of Redhill, Surrey, has since been re-bailed until December 11. His arrest was part of an ongoing Proceeds of Crime Act investigation by officers from the Met's specialist crime directorate. Police would not initially confirm the painting was among a number of items seized.

In the robbery, a number of display cases, doors and other items were damaged by the approximately two suspects who entered the museum and stole an undetermined amount of precious minerals.  It is the goal of State Parks to make the repairs quickly in order to reopen the museum to the public as soon as possible. 

There were two State Parks' employees at the museum at the time of the robbery.  Neither was injured and while both remain shaken from the experience, both report they are doing fine. 

An inventory of the stolen items will be getting underway this week.  Until it is completed, State Parks will not have a listing of what was taken or the dollar amount of the items.

The exhibition aims to raise awareness of the general public the hard work done in recent years by the Judiciary, flanked by Carabinieri Cultural Heritage Protection, with the Guardia di Finanza and the archaeologists of the Superintendent [Soprintendenza per i Beni Archeologici dell'Etruria meridionale], which has led to some important results, perceived not only through a high number of artifacts recovered, by especially in the significant drop in illegal excavations at the archaeological sites of Cerveteri, Vulci, and Tarquinia, once the subject of real raids [translated with the help of Google].

The landscape is intentionally blurred and indistinct.  Fast-moving swirls of green, purple and pink and a splash of white mimic the motion of the water and the wind.  The viewer glimpses the river through a scrim of shrubbery, while something gray and vertical looms on the far bank.

"Paysage Bord du Seine" (On The Shore of the Seine), an oil on linen napkin, measuring 5 1/2" by 9" with no artist signature had been purchased for $1,000 in Paris and valued at $2,500 in 1951 when it was exhibited at the BMA in the show "From Ingres to Gaugin".  Mrs. May told the museum that 'Renoir painted this landscape for his mistress, at a restaurant on the Seine - thus the linen napkin.'  The museum index card noted that this Renoir landscape was stolen from the Gallery on November 17, 1951 and had been replaced by a Degas "Self Portrait".

In a box full of Saidie May's letters and artwork receipts lay one major clue: records showing that she had lent the painting to the museum in 1937.  The discovery startled museum officials, who had already said the flea-market Renoir never entered their institution.
