An original production cel from the Children's Television Workshop Studios animated Sesame Street segment 1 to 20 Number Elimination (c. 1970s). Featuring Cookie Monster eating the number 17, the hand-painted cel was created at the studio and used during the animation process. The piece is an actual frame of animation that was photographed and appears in the short. Measuring 10.5"x12.5" overall, and with the image area measuring 6"x7", the production cel is in good condition with pin holes near top edge of cel. The cel is paired with a color copy reproduction background.
