Snow White isn't even my favorite Disney movie. Sleeping Beauty and Beauty and the Beast are much stronger contenders. I would be absolutely thrilled to see them get the same treatment that Snow White gets here.
This book is absolutely full of art from every stage of the development of Snow White: concept art, storyboards, ruffs, and finished cels. Absolutely gorgeous stuff. I think we all tend to forget, more than 75 years later, what a breakthrough Snow White was as a film. What this book showed me, more than anything else, was the sheer amount of thought, and second thoughts, that went into making the movie.
A must for fans of Disney animation, especially for anyone interested in the process as well as the end product.
