Archaeo-Blogger David Gill notes that the Carabinieri have provided a DVD to certain antiquities dealers of artifacts recovered from a Swiss warehouse in 2001 that are apparently subject (again) to seizure: http://lootingmatters.blogspot.com/2010/01/have-you-seen-this-krater.html
In so doing, he posted but did not directly answer the following question:
David- Could the release of this material be a response to Bill Pearlstein's complaints during the interim review of the Italian MOU that the Carabinieri and US Customs were playing "gotcha" with American auction houses and collectors? See http://culturalpropertyobserver.blogspot.com/2009/11/gotcha-italian-style.html
Instead, Gill reiterates the AIA line that auction houses (and collectors) should only collect artifacts with a solid pre-1970 provenance. But, of course, this does not account for what to do about "orphan artifacts," and, in any event, a 1970 provenance is no "safe harbor" for the likes of Zahi Hawass and friends.
A knowledgeable collector of Greek vases has proposed something more modest. Why can't the Carabineri post images of this material on-line and make it easy for collectors, auction houses, dealers and museums to check whether they have inadvertently purchased artifacts with a questionable provenance?
"Cultural Property Observer" supports that idea, and also asks, "Why does it always seem that that ideology must trump common sense?"
