I don't know who made these attractive crystal iced tea stems or footed tumblers, but the Art Deco arches, pendants, and leaves cutting was done by Lotus Glass in the 1930s to early 1940s. This same ice tea blank with a different cutting is identified as Lotus-Glastonbury on a certain replacement service website.
They're just under 7 inches high by 2-3/4" diameter at the rims and hold 12 ounces to the rims. The cutting features four overlapping arches, two filled with trellis lines, two plain. A circle and leaves pendant is at the point of each trellis arch. The plain arches have cascading leaves extending from the circle pendants. The bases are cut with the smaller triple leaf motifs. The glasses are in excellent, crystal clear condition with no damage or scratches. I did get some fingerprints on them in my hopeless efforts to photograph the lovely design. Price is for the set of three.
