vintage Heisey colonial panel pattern champagne glasses, heavy crystal clear glass stemware

Unmarked Heisey (or Imperial?) glass champagnes in the colonial panel pattern. These are 20th century vintage glasses in the style of antique flint glass, really lovely.

It's a set of six glasses are in excellent condition, without damage or wear. They're 4 1/2" tall, 3 3/4" across the rim - they'd make good modern cocktail glasses if you use flutes rather than coupe bowl glasses for champagne.
