Unknown Disney Animation Sheets (Patreon)

I bought this 33-sheet set of untitled sheets earlier, which I believe belongs to a production that ended up never being animated by Walt Disney Japan. The seller thought it might be at least around 30 years old.

Looking through them, it appears to possibly have been an idea for a Christmas movie, as it features a Christmas-themed creature named Famron and two musicians; Taku, Shinichi, and a girl named Yuki who's dream is apparently to be a horse-racing jockey.

I've attached the rar with the sheets below. Enjoy!
