vintage champagne / cocktail glasses set of 8, iridescent luster glass stemware

Mid-century mod vintage iridescent luster glass cocktails or champagne glasses - these are lovely, like soap bubbles! They're about 4 3/4" tall x 3 1/2" across the bowls.

I'm not sure of the maker, maybe West Virginia glass? Optic pattern glass with a star on the foot. All eight glasses are in very good condition, no chips, color looks very good without wear.
