Monday’s ad is for Colt 45, from probably the late 1960s or 1970s. Most of the malt liquors seemed to advertise its sex appeal — god knows why? — so the play on words with “six appeal” is at least a little clever. And how about that hard plastic six-pack holder. I can’t say I remember those, but they must have been used before the softer ones that are ubiquitous today.
