Gill and Christos Tsirogiannis have written on "Polaroids from the Medici Dossier: Continued Sightings on the Market" for the fifth issue of The Journal of Art Crime (Spring 2011) which can be purchased through subscription through ARCA's website or individually through Amazon.com. This is the abstract for the article:

The series of returned antiquities to Italy have been a reminder of the role of Giacomo Medici in the movement of antiquities to North American public and private collections. A dossier of images was seized during a series of raids on premises in the Geneva Freeport linked to Medici. Such images have made it possible for the Italian authorities to make identifications with recently surfaced antiquities. In spite of the publicity some involved with the trade of antiquities continue to offer recently-surfaced objects that can be traced back to Medici and his consignments to the London market.
