Set of 3 Vintage Smoked Glass Cups with Stripes, Dominion Glass Old Fashioned

This is a lovely matching set of 3 glasses made by Dominion Glass in the 1970s/80s. They are a "smoked glass" colour, which is slightly brown in tint, and have lovely stripes running horizontally across them in tan, yellow, blue, red and orange. They measure approximately 2 7/8" tall and 2.75" across and have significant weight to them. I would describe them as an Old Fashioned drinking glass.
