I'm not sure how old these are but they look like they go back at least to the 80's if not before. Kind of a shame that they don't even call it Dunkin Donuts any more but these cups will keep that name alive in your mind anyway. Nice image of their Logo. No damage or wear. Simply marked U S A on the bottom. Same image on each side of the cup. "TIME TO MAKE THE DONUTS"!!!!
