Sunday’s ad is for Carling’s Red Cap Ale, from 1950. In this ad, part of another series featuring well-known celebrities of the day and the tagline “x person, too, has graduated to Carling’s — the LIGHT-HEARTED ale!,” it features “American sportscaster and public address announcer” Clem McCarthy wearing an Oxford cap, or mortarboard, with a small red cap on top of it while holding up a glass of Red Cap Ale. “He also lent his voice to Pathe News’s RKO newsreels. He was known for his gravelly voice and dramatic style, a “whiskey tenor” as sports announcer and executive David J. Halberstam has called it.”
