I don't generally pick up stemware if I don't have a pretty good idea of the maker, if not the pattern name. But I love the knob pattern stems, and these sparkle so prettily with the very elaborate pattern on the bowls.
I do know these are vintage, and all six glasses of this set are in very nice condition without chips or scratching / dulling. These are large and low (4 1/4" across the bowls, 4 1/2" tall). Cocktails or champagne glasses.
