A little more than two weeks ago, following a second set of seizures at the residence and office of Michael Steinhardt in New York City, ARCA wrote a blog post outlining other antiquities from the billionaire's private collection that have raised concerns with illicit trafficking researchers.  

One of those objects was this marble Female Idol of the Ozieri Culture from Sardinia. 

Tsirogiannis had matched the antiquity online via Christie's web version of its sale catalog to a photo contained in the confiscated archives of antiquities dealer Giacomo Medici.  Having made the ID, Tsirogiannis emailed his concerns to US Federal law enforcement and Italian law enforcement authorities working towards eventual repatriation should Italy file a claim.  Additionally he notified ARCA, in hopes of drawing further attention to potentially trafficked pieces that often resurface on the licit market but which omit passages through the hands of known dealers involved in the sale of illicit objects.

The sales catalog for the Christies auction is stored online here, although the photo of the idol has subsequently been removed from the object's accompanying Lot description.  Of note is the addition of a brief entry into the "Cataloguing & details" section of the listing, which states only that the object was withdrawn from the sale.

The artifact above matches perfectly with the image below which Tsirogiannis located in the dealer's archive.   In the art dealer's records the statuette appeared atop a turquoise background and broken in multiple pieces, prior to the object's subsequent restoration.

Before arriving in the collection of Michael and Judy Steinhardt in 1997, the Ozieri Culture idol, also known as the Turriga Mother Goddess figure, passed through Harmon Fine Arts and the Merrin Gallery, both of New York.  Once part of the collection of Leonard Norman Stern, the object had been displayed, but not photographed, in a 1990 "Masterpieces of Cycladic Art from Private Collections, Museums and the Merrin Gallery" event where both Steinhardt and Stern were present. 

On November 27, 2014 when the contested object was pulled from the Christie's auction, it apparently was sent back to Steinhardt, where it was later re-identified as still being part of Steinhardt's collection when officers searched his New York City home on January 5, 2018 pursuant to an earlier search warrant.
