Portrait of a Young Man (Raphael)

Still missing since 1945. The Czartoryski family rescued Raphael's portrait from their museum in 1939 and hid it at Sieniawa, where the Gestapo, working for Hans Frank, Hitler's governor of occupied Poland, found it. Frank displayed looted paintings in his Kraków residence, and the portrait was last seen there in January 1945. After the war it was among 844 objects missing from storage. Polish officials have said for years that they believe it survived the war, but its location remains unknown, and Poland still lists it among its most important wartime losses.
