mid-century mod vintage hollow stem champagne glasses or cocktail glass set of 6

Set of six vintage hollow stemmed champagne or cocktail glasses, in excellent, unused condition.

These aren't marked, and I don't know the maker - they look like Dorothy Thorpe to me, but plain, without the silver band. Very mod, 'bulbous' shape!

They're 4" across the bowl, about 5 1/4" tall.
