Researchers combing through the Dresden State Art Collection have reportedly discovered for the first time a major work that appears to have been looted by Nazis.

Junge Dame mit Zeichengerät, an 1816 work by Carl Christian Vogel von Vogelstein, was deemed to have been stolen from Jewish owners in 1938. The Art Newspaper reported that the painting belonged to three Jewish sisters in Vienna: Malvine, Jenny, and Bertha Rosauer. They were deported to concentration camps and their property confiscated.

Dresden acquired the painting in 1940 from art dealer Julius Böhler for 4,500 Reischmarks ($1,100). Böhler had bought the work two years earlier from a Viennese art dealer known as Gussenbauer.

The Dresden collection covers 12 museums, and most of its works were acquired before the Nazis came to power. But it, like many museums in Germany, is examining its collection for art that was looted during World War II.
