Our 26th Guinness poster by John Gilroy features a lumberjack energized by drinking his Guinness so that he’s able to fell a large tree with one fell swoop of the axe. “Guinness For Strength,” indeed.
Unfortunately this is the best image of this ad I could find. If anyone has a better one, please let me know or send it my way. There’s also a variation on the lumberjack theme, with the same artwork but a different slogan, “My Goodness, My Guinness.”
