4 Vintage Floral Etched Clear Crystal Stemware Cocktail Wine Glasses Unmarked For Sale

Two slightly different sets of these crystal goblets with a unique etching on them that I do not recognize if someone knows the pattern. Please let me know. I’ve been told that they were her mother’s and she’s 80 so that would make them quite old. Only problem is I’m just not sure. Please see photos ask questions. I will combine shipping on any of my items. Thank you for shopping.
