MOON MULLINS AND POPEYE IN "STEPPING OUT"; J. Souerballs Presents. A Master Mind Production Based on characters created by Frank Willard and E.C. Segar The cover says this is "Directed" by "Elmer Zilch" which is a common Tijuana Bible Pseudonym.
This Tijuana Bible is one of those ancient collectibles you find at places like Abebooks from established rarebooks sellers. I don't know if I could ever trust ebay sellers for selling authentic versions instead of reproductions made to look old. I'm just repeating the above bibliographic info from the Abebooks seller here so that if nothing else, e-hentai will become the historical archive for this 8 page item after every other site has deleted or disapeared. https://www.abebooks.com/MOON-MULLINS-POPEYE-STEPPING-OUT-Souerballs/14224623312/bd
Tijuana Bibles were the 1930's circa smut booklets. There were lots of these little stapled booklets published as part of the precursor industry before the mass-produced commercial pornography industry that we know of today. You can find these small booklets collected in the "THE TIJUANA BIBLES: AMERICA'S FORGOTTEN COMIC STRIPS Vol. ##" multi-volume set. Each volume ## reproduces about 25 of these little stapled books. Sometimes, libraries will do inter-library loans for free (limited number of transactions per year per patron), so if you really must see more of these in your hands, check with your local public library, and if it isn't in stock in paper form (unlikely, ha ha) or accessible via ebook, then you'll have to ask about inter-library loans and if there is a cost. Anyways, my library gets many of these kinds of rare books in ebook form because there are giant ebook services out there which basically scan scarce books and then make them available via service fees to all the public libraries, researchers, companies, and database connections. Of course they remit a royalty to the publisher and author.
