A great article from PhotoParade!
As I looked at the article today, I realized that the Comparative Size Model Sheet featured in the newspaper article was the same as a publicity still I have from 1936 (shown below).
Frankly, I don't know how Dave Smith and the rest of the crew at Disney Archives keeps track of all their millions of items. I think my database work on the collection has been a real plus, but maybe there is some museum class on database construction I should have taken...
Following the Publicity Still is the rest of the publication. Frankly, it's my favorite because you can see the faces of those that were the voices in the movie AND you can see some of the similarities between the actors and the movie characters... NOTE: be sure and check out the photos of Pinto Colvig (more widely known as the voice of Goofy).
