Wow - mystery solved! Many thanks. Have found a photograph on the internet for Consolidated "Dance of the Nymphs" and that's definitely what we have. We have a set of 10 plates, plus 10 smaller plates/shallow bowls - sadly a number are damaged.
You're a wealth of information. I've just begun to be interested in collecting glass, but am very much at the "I-don't-know-much-but-I-know-what-I-like" stage. Hope to learn more from all of you.
Thanks again! :lol:
