The selection of watercolours, which depict views across the vast areas of farmland with a distant church spire on the road, village scenes and rows of factories, could fetch 150,000 pounds at the auction, 'The Daily Telegraph' reported.
The paintings have come to light after they were found within a large estate in Austria's north by an unnamed lawyer who bought the property.
Richard Westwood-Brookes of Mullocks Auctions said the Fuhrer would paint night landscapes for tourists to try and earn a living. "His daily activity was to go out and paint -- he was penniless," he said.
He added: "He tried to get into an academy in Vienna to pursue a career as a professional artist but had two applications turned down.
"He simply wasn't good enough, particularly when drawing people the perspective was all wrong. There's been a lot of research done into the rejections and some labelled it as a turning point in history.
"If he'd been given a place in the academy the most we'd ever heard of Adolf Hitler would have been that he was a routine artist painting some nice landscapes. Researchers believe because he was rejected, it could have turned his mind into deep resentment and eventually into monster he became."
The auction will take place at Ludlow Racecourse, Shrops, on September 30.
