Friday’s ad is for Val. Blatz Brewing and it’s from an old postcard apparently showing a reproduction of a painting that was apparently in a place in Milwaukee, Wisconsin, operated by the Blatz Brewery. Here’s what it said on the back of the card. “This card was mailed from Old Heidelberg Inn, which is maintained for the benefit of visitors to Milwaukee by the Val. Blatz Brewing Co. — brewers of the famous Old Heidelberg, Ester-aged.” I wonder what “Ester-aged” is?
