This is my favourite cartoon character—a four-headed bulldog—based on the Greek Myths dog, Cerberous who guarded the underground (he actually only had three heads). Under the brilliant art direction of Heinz Edlemann this character appeared in The Yellow Submarine (1968) which was based upon the song by The Beatles who also gave their voices to the characters of John, Paul, George and Ringo, and who's mission was to save Pepperland from The Blue Meanies by playing music under the guise of Sergeant Pepper's Lonely Hearts Club Band. The cartoon style of this film was in keeping with the explosion of design and youth culture in the late 1960s.
