These are a pair of Chyna “collectables”- a plate, and a mug.
I believe the plate was made and sold by The Franklin Mint kind of like those Gone With The Wind plates that they sell as being something that will increase in value, but really it’s just a mass-produced piece of crap with zero collectable value.
Ironically, there’s just something about Chyna (and no, I don’t mean her appearance) that makes me lose my appetite…
