Thursday’s ad is for the English brewer’s “Beer is Best” campaign, from 1938. The campaign began in 1933, and ran for 30 years. This one simply shows a man’s arm (wearing a suit) holding a mug of beer. The ad copy wants people to keep drinking English beer, offering several reasons why you should. “Drink beer because you like it” and “Drink beer because it’s good for you.” But whatever you do, “Stick to beer.”
