A 10¢ flea market buy several years ago got me a coverless copy of HELP! magazine. But not just any issue, this is the February 1962 issue containing Will Eisner's Spirit and the infamous "Goodman Goes Playboy" story, which got Kurtzman, Elder and publisher Jim Warren sued by Archie Comics.
The HELP! front cover I found on the Internet.
