Tuesday’s ad is for Bier Ist Gut, from 1952. From the late 1800s until the 1950s, poster art really came into its own, and in a lot of really cool posters, many of them for breweries, were produced. This poster is titled “Bier ist gut,” which of course means “beer is good. But who commissioned the poster and for what purpose continues to be elusive so I don’t know what it was for. The poster was created by Swiss artist Paul Gusset.
