40s 50s vintage hand painted glasses, flowered glass tumblers set

Mid-century vintage hand painted glass tumblers set, six 5 1/2" tall glasses all in excellent condition. The pattern is a white trillium floral pattern with green grasses.

I don't believe these are one of the Hazel Atlas or Fire King Gay Fad patterns - possibly Bartlett Collins?

Or more likely Blue Ridge - this seems like a Blue Ridge or Southern Potteries pattern china we've had before, though I don't seem to be able to find our old photos right now.
