Would really appreciate some information regarding a drawing Nick Mason did on canvas titled "symbol of hope" for the charity whateverittakes.org, I can't download a picture of it but you can see a copy of it if you search "brain damage pink floyd nick mason canvas drawing" my question is that i purchased one of these on the basis that mine is the original hand drawn one that was copied to make cheaper canvas copies to sell in bulk for the charity,it is very very difficult to tell wether mine is the original or just a copy,the reverse of my canvas is sealed with a picture of Nick and a copy of all the 9 celebrity drawings that were donated to the charity, does anyone have any information or knowledge about this item....regards Matt
