The New York Times ran this interesting report about a former Italian culture minister, Francesco Rutelli, trying to stop Bonhams from selling “several archaeological artifacts that he contends may have been looted in Italy. He said he had given Italian prosecutors information regarding the possibly illicit origin of the unidentified objects, which are to be offered at Bonhams on Wednesday as part of an antiquities auction of nearly 400 pieces. He also put the issue to the Italian Parliament, demanding that the government act.”
Bonhams says no one has contacted them about the items. They would be happy to help if someone with the right documents got in touch with them.
