Thursday’s ad is entitled Picnic at the New Homesite, and the illustration was done in 1951 by John Gannam. It’s #54 in a series entitled “Home Life in America,” also known as the Beer Belongs series of ads that the United States Brewers Foundation ran from 1945 to 1956. In this ad, two couples are having a picnic in an unlikely spot. At a construction site, where presumably one of their homes is being built, they’re having beer and food while other people are working. It’s the weirdest spectator sport ever.
