More and more art looted in World War II is coming to market. “Since 1996, Sotheby’s and Christie’s alone have sold a combined total of about £140 million ($252 million at today’s exchange rate) of art returned to families from museums and private collections. As more and more art, primarily looted by the Nazis as well as the Red Army, is being identified and returned, it is becoming an increasingly important source of supply for the auction houses.”
