For sale: 1914 watercolour, by artist Adolf Hitler

A 100-year-old watercolour of Munich’s old city hall is expected to fetch at least €50,000 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 said the painting is one of 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.
