Tuesday’s ad is for Blatz Beer, from 1950. The ad is part of Blatz’s “I lived in Milwaukee, I ought to know” series from the later Forties and Fifties that featured prominent celebrities, sports figures and famous folks from Milwaukee claiming to know “Blatz is Milwaukee’s Finest Beer” because they lived there, or near there, at some point in their lives. This one features prominent adventurer Osa Johnson, who along with her husband Martin, wrote books and made films about their travels. As for her connection to Milwaukee, there doesn’t seem to be much beyond her declaration that she’s “done a little ‘exploring’ in Milwaukee as well as in jungles all over the world.” Plus, she apparently “summered there for eight years.” Because if you were a world-traveling adventurer, Milwaukee is where you’d spend your summers, right?
