“There are some images that are just wrong: uncanny, creepy. One of them is a poster of a smiling, steel-helmeted Nazi-era German soldier holding a pint of stout, with the words in Gothic script: “Es ist Zeit für ein Guinneß!”.
“What makes this poster even weirder is that it’s by John Gilroy, the artist who produced so much classic Guinness advertising imagery, from the flying toucans with glasses of Guinness on their beaks to the Guinness drinker carrying the huge girder. Even people born decades after those ad campaigns ended know the posters.”
