These four cups were kept in storage unused and therefore are in excellent condition. I have found none others like them. Like the Star Wars cups from this era they likely remain rare especially with licensed college branding since a lot of the Clemson merchandise was bootlegged and homebrew in the 80's and prior. These have limited fading but you might catch a slight yellow tint. They could date up to the early 90's but are still over 30 years or more old.
