Overview
This is a vintage Mid-Century Modern lowball/tumbler drinking glass featuring a bold geometric Harlequin diamond pattern framed in turquoise with red accent lozenges. Pieces like this defined the atomic-era home barware explosion of post-war America.
Story
Post-WWII suburban entertaining created a massive boom in decorative cocktail glassware. Designers embraced vibrant optical patterns and bold geometric motifs to bring high modernism straight onto the family patio bar cart.
Maker / Origin
During the 1950s and 60s, American glass giants like Libbey, Hazel-Atlas, and Federal Glass, alongside decorating houses like Culver and Georges Briard, competed to create the most stylish barware sets for the booming middle class.
Condition & Value
The glass appears clear with bright, intact enamel graphics and no obvious fading, rim chips, or dishwasher hazing. Excellent vintage condition preserves its decorative appeal.
