Sheena debuted in Joshua B. Power's British magazine Wags #1 in January 1937.
She was created by S. M. "Jerry" Iger who ran his own small studio, "Universal Phoenix Features" (UFP), and who commissioned Mort Meskin to produce prototype drawings of Sheena.
UFP was one of a handful of studios that produced comics on demand for publishers and syndicates, and whose client Editors Press Service distributed the feature to Wags.
Saying he could no longer afford to pay Will Eisner as a freelancer, he co-founded Eisner & Iger, which continued the work of UFP, but Iger bought out Eisner when (according to Iger) Eisner went to produce propaganda for the US Army but other sources say Eisner left so he could create The Spirit.
To help hide the fact their studio consisted only of themselves, the duo signed their Sheena strip with the pseudonym "W. Morgan Thomas".
Eisner said an inspiration for the character's name was H. Rider Haggard's 1886 jungle-goddess novel She.

Sheena first appeared stateside in Fiction House's Jumbo Comics #1, and subsequently in every issue (Sept. 1938 – April 1953), as well as in her groundbreaking 18-issue spin-off, Sheena, Queen of the Jungle (Spring 1942 – Winter 1952), the first comic book to title-star a female character.
Sheena also appeared in Fiction House's Ka'a'nga #16 (Summer 1952) and the one-shot 3-D Sheena, Jungle Queen (1953)—the latter reprinted by Eclipse Comics as Sheena 3-D (January 1985) and by Blackthorne Publishing as Sheena 3-D Special (May 1985).
Blackthorne also published Jerry Iger's Classic Sheena (April 1985).

Fiction House, originally a pulp magazine publisher, ran prose stories of its star heroine in the latter-day pulp one-shot Stories of Sheena, Queen of the Jungle (Spring 1951) and Jungle Stories vol.
5 #11 (Spring 1954).
