Hanna Barbera Animation Cel 1960’s RARE Production Art Autograph vintage Cartoon

Here we have an extremely rare, hand-painted screen used animation cell on scene, matching painted production background ( 1962) featuring both Bill Hanna and Joe Barbera from Hanna Barbera Studios. This set up is autographed by both animation legends. I believe this is the only on screen animated appearance these to have ever made.

Amazing piece! This may be the only one with a painted background that exists!
