This posting is a tad morbid due to the artist, not the art itself. Adolf Hitler was a painter and deeply interested in art. He produced hundreds of works and sold his paintings and postcards to try to earn a living during his Vienna years (1908–1913). However, he was not successful. A number of his paintings were recovered after World War II and have sold at auction for tens of thousands of dollars. Others were seized by the U.S. Army and are still held by the U.S. government.
His paintings are preoccupied with architecture such as public places, buildings, and farmhouses. During World War II, Hitler used to paint watercolors with war-ruined buildings as a theme. One modern art critic was asked to review some of his paintings without being told who painted them and judged them “quite good”. The different style in which he drew human figures, however, the critic said, represented a profound disinterest in people.
Here’s some samples. You can view more at Hitler’s Historical Museum’s website here.
