In a comment a few posts back for one of the puzzles, I alluded to a model sheet used by the Character Merchandising Division, here is that model sheet.
Tobler postcard that I posted back in the first year of the blog.
This is the only vintage CMD model sheet I've ever come across, dated January 1950 via the code A-1-50. There certainly must be others for each of the main characters, but none have surfaced to my knowledge. But, there are a whole lot of animation model sheets, at least 25 that I am aware of. Stay tuned!
