The reputations of some of the world's most prestigious museums have been damaged by accusations that they obtained antiquities that were looted or stolen in violation of international laws and treaties aimed at halting illicit trade in art and antiquities (Ron Stodghill, "Do You Know Where That Art Has Been?" New York Times, March 18, 2007). A new wariness among private and public collectors to buy works whose provenance has not been rigorously established jeopardizes the business of even the most established dealers. Conversely, this fear has increased the value of antiquities that have a solid ownership history. The Aboutaam brothers, who are among the world's most powerful dealers of antiquities, back an international ban on trade in excavated antiquities. As Hicham Aboutaam said, "The more questionable works entering the antiquities market, the less their value and the larger the dark cloud that hangs over the field. That affects prices negatively. I think we could put an end to the new supply, and work comfortably with what we have."
