This is a experienced collector and he opened his collection as a museum back in 1996. He is always on the look out for interesting objects and one day he saw a framed painting on an auction. This was said to have been painted by Hitler, but as it is so much fakes noone had bought it and it wasn`t a high price for it either. He took the chance and bought it, never really believing it was something else than just a good fake.
When the parcel arrived he inspected the framed painting and wanting to have a closer look at the painting and the paper he opened the back of the frame that was sealed with brown paper tape. Four sheets of paper fell out as he removed the backing and his heart skipped a few beats when he saw well known Disney figures.
The first thing he did when he had settled down was to check everything under blacklight but there was no reaction and having a huge library he found all his books on Hitlers art and started studying and comparing the style. Other experts was consulted and paper, paint and style all fitted with the theory and hope this was Adolfs work.
Of all the things in this museum I find these pieces of paper to be the most interesting of them all.
Have a look at them and make up your own mind. I have also linked to a couple of news articles about this find.
