Highly regarded German conductor (1886–1944) who became embroiled in controversy with the rise of the Third Reich. Though vehemently anti-Hitler, he was widely viewed as a Nazi sympathizer, which severely impacted his career. Vintage 3.5 x 5.5 German postcard photo, signed in fountain pen in the lower border. In fine condition, with some small corner tip creases, and a bit of irregular ink adhesion to a couple of strokes. RRAuction COA.
