The Brave Tin Soldier
The only version to include the melted heart end, and here, they melt into eachother. In this version, the black goblin/jack in the box villain is the king of the toy room. When his advances to the ballerina are rejected and the soldier defends, he prosecutes and has them executed by firing squad into fireplace. Like the russion depiction, the ballerina chooses to die with the brave soldier she loves.
A one-legged tin soldier is cruelly mocked by other toys because of his deformity. The soldier falls in love with a toy ballerina who is desired by the toy king. The king exercises his military power to get the girl for himself. The tale ends tragically, with a surprisingly graphic execution by firing squad. This is probably too violent and weird for little kids. The cartoon itself is very nicely animated, perhaps even moreso than the other Ub Iwerks fairy tales. There are some celebrity caricature toys, including a Groucho Marx jack-in-the-box.
