art deco vintage cocktail or champagne glasses, hollow stem ruby / crystal hand blown stemware

Set of six vintage hand blown stemmed glasses for champagne or cocktails, hollow stem panel optic pattern. These are ruby with clear foot. They're about 5 1/2" tall x 3 1/2" across the bowl. Three of these have tiny fleabite chips at the rims, but none have scratching or finish wear. So pretty!
