Thunderbolt the Wondercolt (1952)

Thunderbolt first appeared on TV as a puppet character on "Thunderbolt the Wondercolt," a 1952 kids' TV puppet show that was written, created, produced and the puppet manipulated by Bob Clampett. Like The Adventures of Bullwinkle and Rocky before it, this show was originally a puppet show (called "Time for Beany", 1950-1953), and became an animated cartoon. It is said that Albert Einstein never missed an episode of the puppet version of this show.
