Saturday’s ad is for Schlitz, from 1908. In the first decade of the 20th century, Schlitz Brewing, then one of the largest breweries in the U.S. after the industry had shrunk from over 4,000 to around 1,500 in just 25 or so years, did a series of primarily text ads, with various themes. In this ad, Schlitz is touting its purity and concludes that “When beer is pure there is nothing more healthful,” adding “And Schlitz beer is pure. It brings no after-effects, no biliousness.” But more importantly, don’t even think about drinking the wrong beer. “That is why the doctor generally says ‘Drink Schlitz.'”
