The Jungle Jim pressbooks were usually a six-page foldout. I scanned the pages in the order you would see them when initially opening the pressbook. The JJ series had a long run of B (perhaps more C) movies to fill theater screens when patrons would spend hours at the theater; unlike today, where you pay a lot of money to see one movie. I'm sure lots of parents would "dump" their kids at the theater for a few hours so they could experience some freedom from parental duties. William Castle took very good advantage of that with his horror movies and their gimmicks. I pity the poor theater crew that had to clean up the mess after Emergo, after kids used the skeleton for target practice with anything at hand they could toss. Oddly enough, due to copyright issues, Johnny Weismuller's name replaced the Jungle Jim handle. Hence the reason the pressbook says Johnny Weissmuller in Jungle Moon Men. He played himself in the movie. This entry leans toward the fantastical, with an immortal Moon Goddess, pygmies that worshipped her (the Moon Men), and a hidden treasure. Wikipedia notes that plot elements were taken from She: A History of Adventure by H. Rider Haggard.
