Although jungle-themed stories appeared in many of Fiction House's titles, this was of course the one most clearly devoted to the genre. Introduced in the very first issue was Ka'anga, the company's blonde-haired male Tarzan clone, who would later have his own eponymous title for a while. Other popular characters included Fantomah, Daughter of the Pharaohs; Wambi the Jungle Boy; and Camilla, the Jungle Queen.
Popular artists whose work appeared in this title include Matt Baker and George Tuska. Will Eisner provided a few of the earliest covers, when his studio was still providing the content.
