Focus on The Foxes (Marc) and analyze the Provenance.
Jewish investment banker Kurt Grawi purchased the painting in 1928. Following the rise of Nazi Germany, Grawi was forced to sell much of his art collection and was incarcerated in Sachsenhausen concentration camp. He was released after several weeks and escaped to Chile. Grawi still owned The Foxes, however, and sold the painting in 1940 to German-American film director William Dieterle. The painting was acquired by German businessman Helmut Horten in 1961, and he donated it to the Düsseldorf city art collections in 1962.
