This 48-card promo set from Dunkin Donuts that translates to "What is their name?" features caricatures of various celebrities, politicians and athletes (including this one basketball player, Emiliano Rodriguez). Dunkin offered a cooresponding mailer that you could send in to exchange for a free gift as well as entering you into a raffle for one of 25 free bicycles, but you had to fill out the names of all 48 characters correctly.
