Thursday’s ad is for Carling’s Red Cap Ale, from 1950. In this ad, part of a series featuring well-known celebrities of the day and the tagline “I’ve found out,” it features “early 20th-century American sportswriter” Grantland Rice holding a beer and giving his testimonial about why he loves Red Cap Ale.

In some of the ads, the inset box is not blank, but included another person, presumably a regular non-famous person and probably localized for where the ad ran, if not in a national publication.
