Friday’s ad is from 1971 and is for the malt liquor Colt 45. Introduced in 1963 by National Brewing of Baltimore, Maryland, today the brand is under the umbrella of Pabst. In the bright, primary colors of the 1970s, it’s a simple ad, with a blue background showing the beer glass upside down and the common toast, “Bottom’s Up” as a tagline, also upside down.
