NUREMBERG - A 1914 watercolor by Adolf Hitler to be auctioned on Saturday could fetch up to 50,000 euros ($62,685) given strong global interest, a German auction house chief said on Tuesday.Auctioneer Kathrin Weidler said the painting entitled "Standesamt und Altes Rathaus Muenchen" (Civil Registry Office and Old Town Hall of Munich) is one of about 2,000 works Hitler painted from about 1905 to 1920 as a struggling young artist.Asked about criticism that it is tasteless to auction the Nazi dictator's works, generally considered to be of limited artistic merit, she said complaints should be addressed to the sellers - an unidentified pair of German sisters in their 70s."Those who want to get worked up about this should just go ahead and get worked up about it," Weidler told Reuters at her Weidler Auction House in Nuremberg, where Hitler held mass Nazi party rallies from 1933 to 1938."They should take it up with the city of Nuremberg or with those who preserved it. It's an historical document."Hitler wrote in his autobiography "Mein Kampf" that his hopes as a young man of becoming an artist were dashed by his repeated rejection by Vienna's Academy of Fine Arts.
