Technically one might argue that this cannot be the world's largest paper cup, since it isn't made out of paper! This giant concrete cup once had the Sweetheart logo painted on it, because it stood in front of the Sweetheart paper cup factory. Now Sweetheart is gone from both the cup and the factory; the cup has red and blue stripes, while the building houses a furniture outlet.
Directions: 800 Iowa Avenue. The cup is behind a fence but can easily be seen.
