I am trying to find out anything I can about them. I know they were my mother's and she purchased them approx. 30 years ago but I have no idea if they are truly antique or who makes them. The glass is thick with a couple of tiny bubbles within it. The edges are scalloped. There is an inset for the teacup too. Any info on these would be appreciated! I also dont see any name inscribed at the bottom of the plates...
