Friday’s ad is for kühles Bier, or “Cool Beer,” from 1950. From the late 1800s until the 1960s, poster art really came into its own, and in a lot of really cool posters, many of them for breweries, were produced. This may have been part of posters promoting beer by the German Brewers since it’s nearly identical to one with a woman on the beach and another one with a man, all of which were created by German artist Heinz Fehling. But I can only find this monochrome version of this one, so I’m not sure if they actually ever used it in the campaign.
I also found this cover of sheet music for a song called “Das Bier Lied,” of “The Beer Song,” which was also illustrated by Fehling around 1950 or 51.
