Collector cups are one of the best things about eating fast food or getting a Slurpee. What better way to show your appreciation for your favorite franchise than to drink your beverage from a cup emblazoned with its likeness? Back in the day, collectible cups used to be made out of glass, but modern times have shifted them to plastic. We display the best collector cups from both eras in this feature. Grab a straw and drink this up!
