Tuesday’s ad is entitled Fiesta Time in the Southwest, and the illustration was done in 1952 by John Gannam. It’s #73 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, a home in one of the southwestern states has been invaded by exotic cultures, as — presumably one of the three women guests at the party has donned her Mexican or South American costume to perform a dance for “fiesta time,” whatever that means. The others are standing or sitting around drinking beers and watching her, which seems a little weird to me.
