vintage uranium green depression glass lemonade set pitcher tumblers Federal corded optic spiral

1920s or early 30s vintage Federal glass green depression lemonade set, a pitcher and six drinking glasses.

I believe this is the corded optic (spiral rib) pattern, rather than the Diana pattern. Very pretty, and it just glows under a black light.

The pitcher stands about 10 1/2" tall, and there's six of the 5 1/4" tumblers. The entire set is in excellent condition without damage, this doesn't look as though it's ever been used, though it's about 90 years old!
