Thundarr the Barbarian was created by Steve Gerber with significant input from Alex Toth, Jack Kirby, and Mark Evanier among others. It ran from 1980-1981 and featured main characters Thundarr, Ookla the Mok, and Princess Ariel. This 2-cel setup features all three main characters: Ariel on her steed, Ookla on his equort, and Thundarr brandishing the Sunsword. It was likely used as a “bumper” card shown before or after commercial breaks.
