London , England ( CNN ) -- A British auction house plans to sell off newly discovered sketches done by Adolf Hitler when he was a struggling student trying desperately to get into art school . The 12 charcoal and crayon sketches cover `` typical student subjects '' and do n't display a great deal of promise , Mullock 's Auctioneers said . They include two drawings of an elderly woman thought to be Hitler 's mother , as well as studies of objects , landscapes , models , and even a Roman senator . All are signed and some even have Hitler 's Vienna address , Mullock 's said . The sale also includes the original portfolio in which Hitler kept the sketches , which is signed and has his address , Mullock 's said . `` They look quite typical of an aspiring student hoping to get into art school -- tentative and not very certain about his perspective when he 's using pencil and pen , making basic errors by getting the top and the bottom of a candlestick wrong in relation to each other , and so on , '' said Michael Liversidge , emeritus dean of arts at Bristol University in England . Letter by Hitler to Britain sells at auction . The sketches lack technical skill but are `` not so bad that one ca n't imagine him learning . `` But there 's not latent genius here , and not much beyond a moderate school grade , '' Liversidge said . `` Probably if the artist was at school today you would n't encourage him to keep the subject up . '' The sketches have been owned by a professional artist who had them for years in his own collection and for his own interest , said Richard Westwood-Brookes , the historical documents expert at Mullock 's . The artist brought the works to Mullock 's attention . Mullock 's plans to auction the sketches April 15 in Ludlow , England , about 125 miles northwest of London . They 're expected to bring between £4,000 and £6,000 ( about $ 6,100 and $ 9,100 ) each , the auction house said . The drawings all date from around 1908 and 1909 , when Hitler was a `` penniless dropout '' trying to get accepted into the prestigious Vienna Academy of Fine Arts to train as a professional artist , Mullock 's said . The school rejected him twice , so Hitler hung around the city , trying to make a living producing watercolors to sell to tourists , Mullock 's said . The rejection by the academy may have had huge implications for Hitler later in life , Westwood-Brookes said . `` Many believe that it was this rejection that turned his mind and unleashed the monster within him , which was to bring forth so much evil on the world , '' he said . `` ... In a sense , therefore , the academic decision of the art establishment in Vienna can go down as one of the most monumental decisions in all of history . '' Nevertheless , Westwood-Brookes said , `` On the evidence of these sketches , you can see why the Vienna Academy turned him away . ''
The two sketches date from when Hitler was trying to get into art school . All the sketches are signed and some even have Adolf Hitler 's Vienna address . They 're expected to bring about $ 6,100 and $ 9,100 each at auction . Drawings all date from April 15 , when Hitler was a `` penniless dropout ''
