There are some that dad made, and some that somebody else did. The museum foundry also makes some, usually an annual design for each year's Repair Days. The iron ones (and the ones with strange baby-like faces) are somebody else's. The houses, plants, and menagerie of zoo animals are dad's - they are sharing space in the gift shop with his Jefferson cups. The very first of the zoo plates is in Heather's daughter's room, I believe.
