Wednesday’s ad is for Rheingold, from 1958. In the late 1940s and 1950s, Rheingold recruited a number of prominent celebrities to do ads for them, all using the tagline: “My beer is Rheingold — the Dry beer!” In this ad, American actor Gregory Peck is still in character apparently from a western, “The Big Country,” talking about the gold he’s protecting riding “gun” on the stagecoach. But the gold he’s talking about is the liquid kind, Rheingold Extra Dry.
