Developed in the 1890s and lasting into the 1950s, the "pulp" magazine (called pulp due to the kind of paper used) format was a low-cost means of delivering fiction short stories to the masses. In many ways, the pulp magazine was a predecessor to the comic book of today and several famous comic book heroes got their start in pulp magazines.

Thrilling Wonder Stories was one such magazine, in print from 1936 to 1955.

This is the October 1939 issue of Thrilling Wonder Stories. This issue includes:

Blood of the Moon By Ray Cummings

The Hormone Menace By Eando Binder

The Circle of Zero By Stanley G. Weinbaum

The Land Where Time Stood Still By Arthur Leo Zagat

Death Dives Deep By Paul Ernst

The Drone Man By A. Merritt

The Nth Degree By Mort Weisinger

Revenge of the Robot By Otis Adelbert Kline

In addition, the magazine features a selection of science quizzes, reader's letters, editor's comments and other minor features.

Due to difficulties with the restoration process, the magazine's regular art feature, called "Zarnak", could not be included. Several art pieces associated with other stories also could not be included. Also, a "Swap Column" and all advertisements were not included.

Purchase includes both MOBI and EPUB formatted versions of the book.
