Spring is here! In "To Spring," a vibrant 1936 animated musical short, bluebirds are flying overhead, winter snow is melting, and little men are sleeping underground (are they dwarves, elves, or gnomes?). These tiny bearded creatures awake from their slumber to begin their yearly crystal-mining labors that herald in the new season. But not before one last kick in the pants from winter.
