70s vintage Libbey drinking glasses, yellow flowers on green glass tumblers

Set of four 1970s vintage flowered pattern green glass tumblers... these are Libbey glass I think, though they're not marked. They're about 4 1/4" tall.

The floral print is very nice on all, these have no visible wear, no chips or cracks. There's roughness on the INSIDE bottom of these glasses which I guess is original to manufacture, it's a deposit of glass or unpolished glass, not wear or stirring damage.

I love the retro floral pattern and the colors on these tumblers, and it's still easy to wash these. And the 'flaw' is not noticeable on any, unless you spend a lot of time staring down into your glass!
