When I first started this blog in 2005, there wasn’t a whole lot online about Fifties animation. Recently, however, a number of animation directors have been posting about design-oriented ’50s cartoons on their blogs. Here’s a roundup: Ren & Stimpy creator John Kricfalusi discusses the modern color in the 1954 Disney short Donald’s Diary. Michael Sporn offers a nice set of frame grabs from UPA’s animated inserts for the 1956 TV special Our Mr. Sun. Ward Jenkins offers this incredible Flickr set of pre-production art and stills from the 1951 Tex Avery-Tom Oreb collaboration Symphony in Slang. The cleaned-up 35mm frame scans are particularly impressive.
