Yes, it's BILL HANNA and JOE BARBERA! These guys were pretty much responsible for saving animation in the late 1950s. At that time, all of the major motion picture studio's cartoon departments were closing down. Hanna and Barbera, who were at MGM, decided to open their own cartoon studio to produce cartoons for TV. They went on to produce some of the all-time great TV cartoon entertainment ever to be done and to be a tremendous inspiration to all of us cartoon illustrators and animators! The above image is a piece I did based on caricatures by legendary Hanna-Barbera Production Designer, Iwao Takamoto. The faces are inked with a brush while the classic Hanna-Barbera logo is hand-lettered. THANKS, HANNA and BARBERA!!
