Sunday’s ad is for Double Diamond, from the 1950s. Part of the Ind Coope’s “Works Wonders” series, but I’m not sure this one was such a good idea. Suggesting that after a few beers, one might have the courage, and skill, to fight crime seems like a potential liability for the brewery. “But your honor, after a few beers, I just had to assert myself. I couldn’t let him get away with the swag.”
