Early to mid century vintage needle etched crystal champagne glasses - this is a set of six glasses 3 1/4" tall, 3 1/2" in diameter across the bowl.
I'm not familiar with this pattern, but almost every fine glass company in the world produced their own etched patterns for a time, including many specialty patterns made as 'house brand' for the better large department stores. There's actually thousands of different etches!
This has vertical lines or rays stretching up from the center of the bowl. Border is a cross shape, four petaled flower or leaf, four larger lobes around that. All six glasses are in excellent condition, clear and sparkling.
