Disney's The Art of Animation

I was fortunate enough to find this in a junk shop. I believe it to be the first edition of Disney's well known book. The copy I have is from 1958. My favorite thing about this edition of the book is the cover, so simplistic and stylized, suprising for Disney, and the fact that it is so old and discolored makes it look even better. Check out the fantastic BG from 'Paul Bunyan' (artist not credited). We have sleeping beauty character sketches by Tom Oreb and a comparison of Eyvind Earle's concept paintings and the final 'Sleeping Beauty' BG's. I like the concept BG much better! I bet this book would fetch me a penny on ebay, I just can't part with it.
