Friday’s ad is for Schlitz from 1949 showing a close-up of a can and a bottle, with a full beer glass in what appears to be a library setting. You can just make out on one of the leather-bound books that the first word in the title is “beer.” Though there is one discrepancy. Notice that the bottle isn’t even half empty but the beer glass is full. There’s no way that portion of the bottle could fill a beer glass that looks to be at least 12 oz., if not a full pint. Hmm.
