Saturday’s ad is for Summer Bier, from 1956. From the late 1800s until the 1970s, poster art really came into its own, and in Europe a lot of really cool posters, many of them for breweries, were produced. This poster was probably made for Swiss Brewers Association, who commissioned similar posters throughout this period, but I don’t really know for certain. The poster was created by Swiss artist Paul Gusset, and he created a similar one called Bier ist Gut around the same time.
