Wednesday’s ad is from 1939, it’s by the United Brewers Industrial Foundation, promoting the brewing industry six years after the end of prohibition. According to the ad, brewers had bought five million pounds of farm products in those half-dozen years. Barley, wheat, rice and corn, from tree million acres of American farm lands. It’s also one of the earliest instances I’ve seen of the tagline they used throughout the 40s and 50s: “Beer … a Beverage of Moderation.”
