Whiz Comics was published by Fawcett Publishing between 1940 and 1953. It is best known for the first appearance of Captain Marvel, aka, Shazam.
As was common practice during the period, Whiz Comics did not have an issue #1. In fact, the series began with issue #2, and there were two different issue #3s. There were two black and white ashcan issues released in advance of the series titled Flash Comics and Thrill Comics (with Captain Marvel called "Captain Thunder") which are considered by many as alternate variants of the first issue of the series.
This issue includes the exploits of Captain Marvel, Golden Arrow, Scoop Smith, Ibis the Invincible, Lance O'Casey, Dan Dare, and Spy Smasher.
