The publisher of Marvel Comics in the 1960s, Martin Goodman, was also the publisher for a number of men's adventure magazines: "Men", "Male" and "Stag". In these magazines, they included a strip called "The Adventures of Pussycat" drawn by Wally Wood and Bill Ward. These strips were eventually collected, and released as a one-shot magazine in 1968. Inside, it is listed as being printed by Marvel Comics, but there is no Marvel logo on the cover, nor any Comics Code mark. The lack of a Comics Code mark came to be a subtle sign that one might find adult content inside.
