Set of 4 Olympian Therm-O-Ware Insulated Small Flared Cup Bowls

Set of 4 Olympian therm-o-ware insulated small flared bowls or cups (copy of advertisement is not included with the cups) from 1975. There are 2 Bright Green, 1 Sun Yellow and 1 Flame. The outer textured plastic with a Greek-key style design surrounds a white smooth thermo plastic. Each cup stands about 2 3/4 inches high with a 2 3/4 inch diameter opening not including the flared lip. While these could be used as small tumblers, they would be perfect for desserts or sauces for dipping at outdoor get-togethers or parties. There are no cracks or chips. Clean. Marked on the bottom - Olympian with torch Therm-O-Ware Dishwasher Safe Unbreakable. In my opinion, I would never put vintage dishes of any kind in a dishwasher. The advertisement is not included with the cups and is actually for another size tumbler. I just thought it was interesting to show. Thermoware 1-21
