Back before Marvel Comics was its own entity, Marvel was owned by a parent company, Magazine Management Co., who produced a number of magazines alongside their comics output, many of them men’s magazines.
This non-Code approved spy spoof one-shot comic collected a number of strips featuring the titular feline that previously appeared in various mags, and were drawn by a number of noted good girl artists of the day, including Wally Wood, Bill Ward, Bill Everett, and Jim Mooney, with Stan Lee as a contributing writer.
(Like Mad Magazine, they worked around the restrictive Comics Code by the loophole of format – even though this black and white magazine was comic strips, it wasn’t considered a ‘comic book’.)
Magazine Management was bought out by Perfect Film & Chemical Corporation in 1968, right around the time Pussycat here got her only solo outing, and Magazine Management would eventually be formally renamed Marvel Comics Group in 1973 … although several magazines like Stag and Male – which started out as 'men’s adventure’ pulps with fiction, girlie cartoons, and only the occasional pin-up in a bikini, eventually became straight-up cover-to-cover nude pictorials with sexually explicit articles – were published under the 'Magazine Management’ banner until the mid-to-late 1970s, when they were finally discontinued.
Stag had first been published in 1942, not long after Timely debuted Captain America, and had a run of 314 issues until the final one in 1976, long after Spider-Man and the Hulk had become pop culture icons.
And that, kids, is the story of how Disney eventually bought themselves a former porn publisher turned superhero entertainment empire.
