Thursday’s ad is for Blatz Beer, from 1949. 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 character actor Brian Donleavy, who was born in Ireland. When he was around ten, his family moved to Sheboygan Falls, Wisconsin. According to the ad, he also served in the Wisconsin National Guard and lived for a time in Milwaukee.
