1988 U.S. Olympic Team McDonald's Plastic Cup - Diving Team - Diet Coke Logo - Made in USA by Louisiana Plastics, Inc. in St. Louis, Missouri. Listing this as "used" but it is in incredible condition for being nearly 40 years old. No visible cracks or chips and has excellent color with very little fading. I cannot confirm, but this looks like it has never been used and definitely never run through a dishwasher cycle. Great addition to your collection if you are needing the Diving cup!!
