Saturday’s ad is for Blatz Beer, from 1951. 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 harness racer Guy Crippen, who was born in Darlington, Wisconsin, but spent most of his career racing and training horses in Milwaukee.
