Thanks to the one and only David Gerstein I'm able to show this marvelous stuff.
Among the many things you'll enjoy there are a production drawing from the Silly Simphony "Bugs in Love" (for which, by the way, David provided a commentary in the "More Silly Simphonies" Treasures set) and storyboards for "When the Cat's Away" (an early Mickey entry where he and Minnie have the size of real life mice!)
I really liked this one!
Thanks again, David!
Yours,
Duck Dodgers
