Rembrandt Films is the production company started by Gene Deitch to do some different things in animation. They did some very good shorts (they also did the absolutely worst Tom and Jerry shorts ever), but this short, Munro, is sufficient to justify their entire existence all by itself! The basic premise (a 4-year old is inducted into the army) is wonderful and the adaptation of the source material was done by its author, Jules Fieffer. The whole thing comes off beautifully and I am delighted that it's in-print. The compilation it's on is marvelous, with a good many excellent cartoons. Most highly recommended.
