These are two unmarked Reproduction Cobalt Blue Bottoms Up shot glasses.
These Bottoms Up shot glasses were made in McKee vintage style with closed legs.
They are identical, smooth, and are a glossy, deep cobalt blue color.
They measure about 3 1/4” high and 2 3/8” across drinking rim.
These were probably made in the late 20th century, but manufacturer is unknown.
Two shot glasses are offered together in this sale.
I always pack glassware carefully before shipping.
