The mini toy piano is working but is in rough shape. The graphics are still bright and visible. They do not appear to be characters from a well-known anime, manga, or licensed property such as Sanrio, Toei, or Nippon Animation. Instead, this looks much more like original stock artwork created specifically for export toys made in Japan during the late 1960s to early 1970s. This was extremely common among inexpensive toy pianos, music boxes, and tin toys. I can't seem to find any comparable examples that have survived. Size ranges from 12 to 15" at the longest points.
