Tuesday’s ad is for Schlitz, from 1953. “‘Round the clock and ’round the calendar — day in and day out — Schlitz quality is assured by hundreds of special, rigid safeguards.” I understand how brewing works, so what exactly might be these “hundreds of special, rigid safeguards?” As a later series of Schlitz ads wondered, “I was curious.” And I especially love this description of the beer. “The light, dry and winsome flavor of Schlitz sparkles.” I don’t drink nearly enough winsome beers anymore.
