Saturday’s ad is for Schlitz, from 1944. Another magic bottle on the tray, but more curious is the illustration. A bear (cub?) in a band uniform playing a tuba (Sousaphone technically) while sitting on a park bench. What on Earth does that have to do with beer generally, and Schlitz in specific?
In 1944, the Braves were in Boston (they moved to Milwaukee for 1953 season, then moved to Atlanta for the 1971 season). There was a Triple-A team there (part of the American Association) called the Brewers. If they had a bear mascot (which no Major League teams had back then, but some minor league teams did), then the ad makes some kind of weird sense.
