This was published at the period of transition when comic books went from anthologies of newspaper strips to books of original material.
The Sheena story is pretty obviously a reprinted newspaper strip, and very nice too.
Many of the other strips here are laid out like Sunday strips, hence the logo on the top of each page. How many were actually newspaper strips I don't know. At that time, the goal of most creators was to have their own strip. Eisner made it with the Spirit. Kirby did several newspaper strips for short periods of time.
Here we have : Bob Kane, Will Eisner, Jack Kirby, S.M. (Jerry) Eiger, Bernard Bailey, Dick Briefer, Mort Meskin (On Sheena, and very nice work) all in the same book. This was packaged by Eisner and Eiger, "one of the first comics "packagers" that produced outsourced comic-book material for publishers entering the new medium. Eisner & Iger was an immediate success, and the two soon had a stable of creators supplying work to Fox Comics, Fiction House, Quality Comics, and others. Turning a profit of $1.50 a page, Eisner claimed that he "got very rich before I was 22",[12] later detailing that in Depression-era 1939 alone, he and Iger "had split $25,000 between us",[13] a considerable amount for the time."

This book is probably worth a fortune in mint.
