Following the success of Superman in '38 and Batman in '39, others began to publish superhero comics. One such publisher was Holyoke who came out with Strongman in Crash Comics #1. In the fourth issue of that comic, Cat-Man was introduced, raised by a tiger in India (not an ape in Africa like Tarzan) and imbued with cat-like abilities. Cat-Man also appeared in the fifth issue before his popularity, or the lack of it for the Strongman, caused the publisher to turn Crash Comics into Cat-Man Comics. The number on the front page was clearly #1 but in the copyright notice, it was listed as Vol 1, Issue 6.
Cat-Man Comics would survive several years and in addition to the main character and his sidekick, Kitten, there would be a nice variety of other stories. A couple were science-fiction, one or two detective, and several were superheroes. One was Black Friday.
Living a very short life as an adventure series in the pages of Cat-Man, his two tales of spy fighting were as extras in the pages following the main Cat-Man adventure and thus not as long as the star of the publication.
In the first issue he made an appearance (Cat-Man #8), his adventure came after stories about "The Deacon" and "Rag-Man" and before tales of "Voltron" and "Mastermind M'Ginty", "Little Leaders" and "The Hood".
In the second issue, he was immediately following the Cat-Man story, followed by "The Hood", "Pied Piper", "The Deacon", "Mastermind M'Ginty", "The Rag-Man", "Little Leaders", and Voltron.
