IN NOVEMBER German authorities revealed that more than 1,400 valuable works of art had been confiscated from the Munich flat of Cornelius Gurlitt, a reclusive octogenarian. The trove is full of the kind of avant-garde "degenerate" art the Nazis removed from Germany's state museums, such as works by Picasso, Chagall, Matisse and Beckmann, as well as older gems, such as an engraving by Albrecht Dürer. Some of it may have come from Jews who were forced to flee or were sent to concentration camps. Surviving heirs and museums have been coming forward as the rightful owners. How is Nazi-looted artwork returned?
