These watercolor backgrounds from Disney's "Snow White and the Seven Dwarfs" remain among my favorite artwork to this day.
Not many of them remain in the ARL (Disney Studios Animation Research Library) so this artist, Hans Bacher, a well known Production Designer in the animation industry, has lovingly reconstructed some of them using screen captures from the DVD.
Go to his site to see more of his background 'rebuilds' from Disney's first full length feature animation. They are some of the most beautiful illustrations in existence. As a bonus, you can click on the pictures to see a much larger version (which I highly recommend).
