Original Character Color Specification Sheet for 'The Abbott and Costello Cartoon Show'

This is an original hand-painted animation production sheet, specifically a 'color spec' (specification) sheet, featuring the animated likenesses of Bud Abbott and Lou Costello in western attire. The piece is hand-inked on acetate (cel) and painted on the reverse, then placed over a solid orange background. The item features extensive production notations with arrows pointing to specific areas of the characters' clothing, designating color codes such as 'MBL-A', 'YGR-1', and '#5' to ensure consistency across the animation studio. The characters are depicted in a stylized 1960s Hanna-Barbera aesthetic. The cel is housed in a contemporary silver-toned metal frame with a brown mat. Hand-written inscriptions on the lower right of the mat identify it as an 'Original Character Sheet (Color Spec.) Abbott & Costello Film "Westward Ho Ho" BP 150'. A signature, possibly 'John Luyten', is visible on the lower right of the orange background. The condition appears fair to good; while the cel paint remains vibrant, there is some visible rippling/warping of the acetate and minor scuffs on the frame's finish. The piece likely dates to the production of the 1967-1968 animated series produced by Hanna-Barbera and Jomar Productions.

I have completed a visual examination of the original color specification cel from the 1967 Hanna-Barbera production 'The Abbott and Costello Cartoon Show.' This piece is a significant production artifact, serving as the master reference for ink-and-paint departments to maintain chromatic consistency. The characters are rendered in their 'Westward Ho Ho' western motifs, adding thematic appeal. Authenticity appears consistent with late-1960s production techniques, including hand-inked line work on acetate and traditional gouache-based paint on the verso. The 'John Luyten' signature suggests a connection to the production staff or a former studio collection. However, the condition is a primary concern. I note visible 'cockling' or warping of the acetate sheet, which is common in older cellulose acetate but can lead to future paint delamination if not stabilized. The framing is functional but does not appear to be of museum-grade archival quality. The market for 1960s Hanna-Barbera material remains steady, though color specs typically command less than key master setups with hand-painted backgrounds. Comparables for secondary character specs from this era range from $300 to $800, with iconic duos like Abbott and Costello sitting in the mid-range due to their nostalgic crossover appeal. Limitations: This appraisal is based strictly on digital imagery. A full authentication would require an in-person inspection to check for 'vinegar syndrome' (chemical decay of the acetate), verification of the signature's authenticity, and examination of the paint-to-acetate bond. Provenance documentation from Hanna-Barbera or Jomar Productions would be necessary to certify the item’s chain of custody and maximize its market value.
