Friday’s ad is for Bock Bier, from 1890. 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. This poster is for Bock and features Gambrinus riding a beer keg being pulled by two goats. The poster was published by Adolf Engel, Royal Court Press and Publishing House Berlin, Germany.
