Paul Cardew Designs Disney Christmas Tree Ornaments Mini Teapots Mickey Mouse, Donald Duck, and Goofy All Limited Edition and numbered, PLUS a SANTA similar ornament, same size. Perhaps the Santa is a knock-off, or a very early Cardew unnumbered item.
Mickey is #7500 of 7500 (the very last one!).
Pluto is #3582 of 7500.
Donald is 2216 of 10,000. Donald came off his box and has been gently glued back on. Signs of glue are visible if examined very closely.
Santa has no markings on base. Santa's teapot handle and spout emerge from the box corners, the others' from the sides.
