Sunday’s ad is for Ein Bier mit Dir, or “A Beer with You,” from 1952. From the late 1800s until the 1960s, poster art really came into its own, and in Europe a lot of really cool posters, many of them for breweries, were produced. I believe this poster was made to promote Swiss beer by the Swiss Brewery Association.  The artist who created the poster was Swiss artist Alfred Koella.
