VINTAGE CHINESE WALL HANGING COASTERS??

I'll be honest. I have no idea what these actually are. the closest thing I could find online was what I listed in the description. They sure are pretty. As you can see, they are no bigger than my hand. Each one has a different scene of what looks like some kind of laser cut metal or vinyl with a red vinyl ring around the picture and a black felt bottom. there is a set of 6, and they come in a black square box. Each one has a different scene.
