(Hanna-Barbera Studios, 1985) Original production key master background set-up from the animated television series The 13 Ghosts of Scooby-Doo. The set-up contains production cels of Shaggy in a full-length pose holding an eerie chest, with Daphne Blake hiding and peering over his shoulder, which is placed on a hand-painted production background from the same scene; the detailed background appears to depict the creepy interior of a cave with sandy floor, rock walls, and stalactites. The cel images, which are marked “252, E2” and “252, D1,” measure to a total size of 3 x 6, and the background, which is marked “0035-8503, BG55,” measures 13.75 x 10.5. The lower left corner bears an affixed Hanna-Barbera 'Original Hand Painted Production Cel' label. In fine condition, with light wear to the right side.
