Our 109th Guinness ad is from around 1945, an original by John Gilroy. I’ve never seen a final version of this ad, but I have to assume it was used at some point. It shows a cellist so engrossed in his music, and so strong thanks to the Guinness under his music stand, that he’s sawed his cello in half. I didn’t realize horsehair was so sharp. The tagline is, of course, “Guinness for Strength.”
