Vintage pinch glass tumblers, bubble texture green glass drinking glasses set

Vintage set of pinched shape tumblers with a crinkled bubble texture - we love the shape, and love the retro green color, too!

These aren't Blenko or other designer art glass, they're just ordinary safety rim glasses, probably Libbey glassware? Late 60s or 70s vintage.

These are low-ball glasses, about 3 1/4" tall. It's a set of six, all in excellent condition.
