Thanks again for your input mart I'll research the typical European style of the time period! I appreciate your opinion and it's possible it is a very old reproduction. It was not made in 1997 though it has been in my mothers possession since 1988, the year I was born.
The back of the plate has pits and discoloration which doesn't seem like something a high quality plate would have, please correct me if I'm wrong.
