The Nazi government also saw modern art as a source of revenue, and a way to obtain needed foreign currency. After they removed more than 20,000 “degenerate” works from German museums, the holdings were first stored at the so-called Viktoria-Speicher, a former granary at Köpenicker Strasse 24a in Berlin. Nearly 4,500 of those works were officially declared “internationally marketable” and transferred to a baroque castle in Niederschönhausen, Berlin. Aside from Karl Buchholz, who sold André Derain’s Valley of the Lot at Vers (seen on the upper right) through his partner Curt Valentin to MoMA, three other dealers made use of those holdings in Schönhausen and sold works on behalf of the German government: Bernhard A. Böhmer, Hildebrand Gurlitt, and Ferdinand Möller.
