This sale is for a set of 6 vintage mid-century highball 7" tumblers made of glass with a tri-color coating from the 1960s. These abstract patterned glasses are ideal for all occasions and reflect the Mid-Century Modern style popular during that era. With a unique multicolor design, these handmade, studio-crafted tumblers are unmarked and of unknown origins, making them a rare find for collectors of vintage drinkware. The external colored coating is not glass and the tumblers were probably hand dipped during production. All 6 tumblers are clean and damage-free. There are no chips, flakes, cracks, stains or damages that I see. Please see all of my pics and please contact me with any questions. I will respond promptly........and thanks for looking!
