'Social Climbers (House Painter)' by Bernhard Kretzschmar (1939)
The painting gives rise to two possible interpretations. "Mein Kampf," Hitler's manifesto, sits in the window along with a cover featuring Mussolini. "Is the shop being painted because it has been taken over from a Jewish owner?" wonders curator Dieter Scholz. The second title, "House painter," was a derogatory term for Hitler used by Bertolt Brecht, but was added to the work after the war.
