Oscar has a huge smile on his face * * * Original Animation Cel & Production Background * * Medium: Hand painted acetate celDetails: Animation notations and peg holes * * Size of cel: 10 1/2 x 12 1/2 inchesSize of background: 10 1/2 x 14 inchesCondition: Very good * * * This is an original hand-painted cel set-up used in the production of an episode of "Sesame Street." Each one-of-a-kind set-up represents a slight change in position of the characters. When individually photographed and projected in rapid succession, the images * appear to move. * * To create production cels, the original animator's drawing is transferred onto an acetate cel (by hand-inking and/or photo copying). The cel is then hand-painted on the reverse side.  The background accompanying this set-up is an original hand-painted background.
