LONDON, ENGLAND.- A series of watercolors believed to have been painted by Adolf Hitler are to be sold by a Cornish auction house. The 21 paintings and two pencil sketches will go under the hammer at Jefferys auctioneers in Lostwithiel, Cornwall, on September 26.

“They will be interested not in the aesthetic value of the pictures but in the signature, sometimes AH, sometimes A Hitler. The watercolors are - probably - the work of the young Adolf Hitler, painted while he served on the border of France and Belgium as a corporal during the first world war,” reported The Guardian.

The paintings were done during the World War I "so there is no connection with what he became later", a spokesman said.

The works, mostly watercolors of landscapes, have been put up for sale by an anonymous Belgian owner. They were discovered in an attic near where Hitler served during World War I. Some are signed "A Hitler" and others "AH".

Hitler, who was rejected by the Academy of Art in Vienna, sold some of his early drawings through a Jewish art dealer.
