In addition to having Vermeer’s painting “An (or The) Artist in His Studio” hanging in his Berghof home, Adolf Hitler preferred works by Carl Spitzweg and Eduard von Grützner. His taste in art was, of course, generally conservative. Trivia: Goebbels favored rather modern art until Hitler steered him away from that aesthetic towards more traditional art. Goebbels later favored Dutch masters [1].
