And Hitler's obsession
One of the most pleasantly surprising things I learned about Churchill was that he spent time painting watercolors. He was modest about it, though. And didn't let it influence his politics. I think it was something he did to appreciate nature and beauty, especially after the expensive purchase of his Chartwell House home, whose grounds he often used for painting.
Contrast this with Hitler, a surprisingly competent artist, whose hubris got the better of him, and he decided to experiment with off-the-canvass creation and reconstruct the whole world according to his maligned vision. This, at least, is thesis in Marrakech, about 1948. By Winston Churchill
Yes, and paintings attributed to Hitler do go up for auction. The good news is that they don't bring nearly as much as Churchill's.
