Harvest Flower Reproduction, Gibson
This iced tea sized tumbler was made in the Harvest Flower pattern by Gibson. They are found in blue opal, cobalt, custard, lemon custard, milkglass, red, white and probably other colors. The examples I've see have dates from the 1980s. Any would be valued at under $10.

At the 2019 auction of Bob Smith's tumblers, a group of these sold:
Blue, $10
Green, $10,
Opaline, $10
Red, $5
Vaseline, $15

Also in 2019, a 7-piece water set in iridized Burmese sold for $90
