Thursday’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. 3,” there’s a poem about a turtle who drinks a cup Guinness, of course, and is rev’d up.
