Saturday’s ad is for Schlitz, from 1955. And you thought the blue man group was a new phenomenon, but they were around and serving Schlitz — a.k.a. the World’s Most Famous Taste in Beer — way back in the Fifties. Honestly, I don’t quite understand why the guy is blue. But he does have another one of those magic bottles. It’s only half empty but it managed to completely fill two pilsner glasses.
