Adolf Hitler's art is up for sale and the starting price is 4,500 euros

Berlin: A 100-year-old water-color of Munich's city hall is expected to fetch at least 50,000 euros ($60,000) at auction this weekend, not so much for its artistic value as for the signature in the bottom left corner: A. Hitler.

Nuremberg's Weidler auction house says the painting was one some 2,000 painted by Adolf Hitler and is thought to be from about 1914, when he was struggling to make a living as an artist, almost two decades before rising to power as the Nazi dictator.

It's being sold by a pair of elderly sisters, whose grandfather purchased the painting in 1916.

Auction house director Kathrin Weidler says it's drawn interest from around the world, with most viewing it as a curiosity or as an investment.

The starting price Saturday is 4,500 euros.
