Friday’s ad is for Hamm’s, from 1950. Showing bottles of “Hamm’s Preferred Stock Beer,” with a single can hiding behind them, on a silver tray, this is another case of physics run amok. The can looks like it hasn’t been opened yet, and the two open bottles are each about three-quarters full, yet the two glasses on the tray are filled to the brim. So either they’re tiny glasses (although they look proportionally the right size) or where did all the beer come from? This is a typical oddity in ads from this time period.
