There is a store that cells original animation art at Disney's MGM Studios in Florida....Don't know if that helps! It was pretty cool, they had black and white and colour sketches of every character you could think of, and the artists do them right there in the building. You can wwatch them drawing for upcoming movies...when I was there they were sketching for Meet the Robinsons......If that's no good, you can always try e-bay!
