Thursday’s ad is for Rheingold, from 1955. In the 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 1948 ad, English stage and film actor Cedric Hardwicke, explains that the most unpredictable part of any performance is the audience, but contrasts that with the consistent positive reaction he gets when after a show he orders a round of Rheingold Extra Dry.
