BERLIN - A PAIR of watercolor paintings depicting farm scenes and signed 'Adolf Hitler' are up for auction in the German city of Nuremberg this month.

The Weidler Auction House said on Friday that paintings titled 'Farmstead' and 'Farm Buildings on the River' and listed in its online catalog are attributed to the Nazi dictator.

Auction house owner Herbert Weidler described the paintings as 'average' quality and said they were being offered by a Polish owner, whom he declined to identify.

The watercolors are listed in the catalog as 'signed and dated 1914,' with bidding to start at euro3,500 (S$7,000) at the auction, which runs April 23-25.

As a young man, Hitler sought to earn his living as an artist. He is believed to have painted hundreds of works, several of which have come up for sale over the years.

Weidler said he sold one four years ago for euro11,000.

Another collection of Hitler's artwork was sold in England in 2006. -- AP
