as a painter he is clearly influenced by names like edvard munch and toulouse-lautrec, but often with an independent naivist touch. later on, paul klee and wassily kandinsky seem to have been an inspiration in spite of his often outspoken ridiculing of modern art. among his many themes are "" from paris, from prostitution milieus and nature scenes. "la morgue" (1906) and "kultur" (1908, "culture") are two of his most well known paintings.
