Ersatz, an exceptional piece of work from Zagreb Films, was the first non-American work to win the Academy Award for Animated Short (though it was not the first for an independent studio-depending on definition, that honor would go to UPA or John Hubley's Storyboard, Inc) and deserved to win. It's lively, amusing, well-animated and stretches the envelope. Clearly influenced by UPA, as were most of the Eastern Europeans, I loved this the first time I saw this some 25 years ago, although I found it predictable in spots, including the ending. I saw it again recently and it still holds up. It's available on a tape produced by Rembrandt Films, called The Best of Zagreb Films: The Classic Collection, which may well be in print. Copies are certainly still floating around. Well worth tracking down. Most highly recommended
