vintage Americana red white blue hand painted drinking glasses patriotic drum

Gay Fad style hand painted glass tumblers with drum pattern in red, white and blue. I think these are probably 1970s bicentennial vintage, but could be earlier, 1950s or even 1940s Victory style? I’ve never seen this pattern before.

This is a set of six glasses 5 1/2" tall, all in excellent condition without signs of wear or any damage. Fun for the 4th of July!
