Sunday’s ad is for Guinness, from 1961. While the best known Guinness ads were undoubtedly the ones created by John Gilroy, Guinness had other creative ads throughout the same period and afterward, too, which are often overlooked. In this ad, marked “Guinness Pets Page No. 5,” there are five short poems about several different breeds of dog, all in a humorous vein, and all leading to another Guinness.
