From left to right top shelf:
Left--Very old Chinese plate (many cracks, but repaired and back repainted) that my in-laws gave to us over 25 years ago.
Middle--Gift to my father-in-law while he was in the automobile business.
Right--Another old Chinese plate (cracks and all) given to us with the one on the left.
All I know is "Chinese" plates that hung for years in my in-laws' home.
If I had the time or desire, I would try to track down if they are "real" or valuable. It does not matter to us, since they were part of my hub's inheritance.
We just enjoy them all.
