Sunday’s ad is for Carling’s Red Cap Ale, from 1952. In this ad, showing a hat rack hanging a single red cap and sign reading “Think,” the tagline finishes below. I guess it requires you to think a little bit to put the ad’s text together. “Think … and you’ll drink Red Cap.”
Two years later, in 1954, they were still running essentially the same ad, slightly modified to fit a narrower space in a publication.
