Hardrock, Coco and Joe — The Three Little Dwarfs is a 1951 short stop motion animated cartoon based on a song written by Stuart Hamblen. It is about three of Santa Claus' helpers who ride on Santa's sleigh each Christmas. The short has become an annual "Christmas Classic" first on Johnstown, PA WJAC-TV and then following on Chicago's WGN-TV and since its introduction in the mid-1950s. The film is entirely in black-and-white. The short was originally created by Centaur Productions utilizing the stop-motion talents of artist Wah Ming Chang. Its running time is about 2 minutes and 45 seconds. This cartoon is traditionally broadcast with their two other short Christmas cartoons, Suzy Snowflake and Frosty the Snowman. Centaur assigned copyright on the film to the song's copyright holder, Hill and Range Songs, who renewed the copyright on the film (but not the song) in 1979. ()
