This listing is for an original hand-painted animation production cel labeled âMU41 SLEEPING MONSTER.â
The artwork features a detailed creature design with intricate linework, claws, and eye markings. The cel includes paint codes and internal studio notes such as YG-A, XR-D1, and SP-A, which identify the intended color palette for different body parts.
The cel is placed over a plain white background sheet (for photo visibility only) and does not include a printed or painted background. The paint and ink remain vibrant and intact, showing classic late-20th-century animation production methods.
While the exact show or film has not been identified, the style, labeling, and professional detail suggest 1980sâ1990s studio production workâpossibly from a sci-fi, fantasy, or monster-themed series.
Every animation cel like this represents a single frame of traditional hand-drawn animationâpainted on acetate and photographed in sequence to bring characters and creatures to life. By the 2000s, digital methods replaced this process, making original painted cels like this both rare and collectible.
