At any rate, looking at his work (pictured) you can understand why it wouldn't fly in the early 20th century (except with tourists, to whom he would sell watercolor copies of postcards). It's not nearly edgy or inventive enough to pass in an Expressionist or Cubist salon, but also not sufficiently academic to get him into a state art program. Which begs the question: why are people spending more and more money on his paintings? (In 1960 two pieces were sold for $1,000, and in 1991 two more went for a total of $5,300.) Is it some kind of macabre fascination with evil? Do these collectors just have terrible taste? Is it a neo-Nazi scheme to launder money into Hitler's estate? Whatever it is, it's creepy.
