The Weird Adventures of Rex Dexter of Mars

You have to buy a comic with a title like that!!!

A Fox Feature Comic first issue from Fall of 1940.

Now, the cool story is behind the ad for a FREE bottle of cola. I checked but the Kooba ad was expired. Not that it was of much use. According to the Internet, Victor Fox, who was the publisher behind WonderWorld Comics, Mystery Men Comics, Weird Comics, and other titles featuring The Blue Beetle, Samson, The Flame, and others come up with a scheme involving his comics. He was inspired by the success of Pepsi and Coca-Cola so he decided to promote this Kooba Cola in his entire line of comic books. However, there’s a catch. The cola didn’t exist. All Fox had was a couple of mocked-up bottles used as props and reference for illustrators.

The scheme was to create a demand for Kooba, then license the name to a manufacturer to do the creating, bottling, and shipping the stuff. Fox planned on taking royalties on the name alone. He even added Kooba's "sponsorship" of The Blue Beetle radio show which was only part of the show's script. With no paid ads, the radio show lasted four months. Unfortunately for Fox, the scheme went down in flames as no demand arose for this cola and Fox Feature Syndicate looked for other avenues to build the empire.

This also might account for the fact that there’s only one issue of this comic!

The company eventually filed for Chapter 11 bankruptcy reorganization in July 1950.

Who said you can’t learn anything from comics?
