Thursday’s ad is entitled Friends From Across the Lake, and the illustration was done in 1955 by Haddon Sundblom. It’s #110 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 group of people are in the back of their lakeside cabin at night — but the women still in cocktail dresses — spinning vinyl, listening to music on their portable record player. One of the is waving to a woman down at the dock, apparently Friends From Across the Lake.”
