Wednesday’s ad is for an untitled work I’m calling The Beer Glass, from 1960. 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. I’m not sure if this was part of posters promoting beer by the German Brewers Association, the Swiss Brewery Association, or something entirely different. It was created by Swiss artist Willi Eldenbenz.
Below is a more crude scan or photo of the same illustration printed in a magazine, or book, which gives some idea of how it may have been used. It seems likely that whatever was on the facing page gives this more context.
