The grocery chain was Acme. Does anyone remember them by any chance?
Of course we remember Acme!
And Playboy? Years ago, it was one of the best sources for fiction around. I remember reading Ray Bradbury, Tennessee Williams, Jules Feiffer and, of course, Jean Shepherd (to name just a few) in those pages. I think my favorite story of Shepherd's was "The Grandstand Passion Play of Delbert and the Bumpus Hounds". Classic stuff back then. They were the first to publish a
very risqué essay by Mark Twain ("Some Thoughts on the Science of Onanism"). I still have a few from the '60s and early '70s.
