Saturday’s ad is for is by Ballantine Ale, from 1957. In the 1950s, Ballantine advertised the hop variety “Brewer’s Gold” as “a rare strain of choice hops” and even registered it as a trade-mark, although Brewers Gold is widely available today. In this ad, two couples are spending some time together when one of the sits down at the piano. That could have been the end of the evening, but luckily one of the women quickly got a tray full of Ballantine Ale for everybody. If you’re going to stand around a piano singing show tunes, you’re going to need beer.
