Sunday’s ad is for Schlitz, from 1939. In this ad, entitled “There’s a surprising difference in Hobbies,” which details many ways in which people like to relax, by collecting things or playing with model trains (like my son). But the second half of this double truck ad is devoted instead to “There’s an amazing difference in beers!” But for that there’s much less variety. Spoiler alert: it’s just Schlitz.
