Sunday’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 “American tennis player” Jack Kramer holding a beer and giving his testimonial about why he loves Red Cap Ale. “A World No. 1 player for a number of years, and one of the most important people in the establishment of modern men’s “Open”-era tennis, he was the leading promoter of professional tennis tours in the 1950s and 1960s.”

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.
