One of the paintings in the 1930s belonged to the collection of Jewish factory owner and art collector David Friedmann in Wrocław , then Breslau , Silesia . It was seized by the Nazi authorities shortly after the anti-Jewish '' Kristallnacht '' pogrom in 1938 and became a part of the collection of Hildebrand Gurlitt . After World War II the painting was seized by Allied authorities along with other works from Gurlitt 's collection , but was returned to Gurlitt when he convinced the authorities he was the rightful owner . It was contained in the 2012 Munich artworks discovery and was returned to the heirs of Friedmann by German authorities . The painting was sold at Sotheby 's in June 2015
