Four color comics for just a dime!

With the success of Superman in Action comics #1 new publishers where popping up hoping to catch some of the magic that Superman was. The comics were produced quickly and cheaply so that they could get out there before the craze died down and so that the publishers profit margins could be larger.
One of the very early publishers of comics was Quality Comics. Their first comic was Smash Comics (Aug. 1939) featuring master spy Espionage, the exotic Abdul the Arab, humorous Archie O'Toole, adventurous Wings Wendall, and super robot, Bozo the Robo the iron man and his human friend Hugh Hazzard.

Eisner creating Spirit's four color world!

In the late 30's Superman hit the scene in Action Comics #1 and comic books became a huge business. To fulfill the need for new material, sweatshops like the Eisner/Igor studio popped up and created new comic pages in an assembly line process.

They were made cheaply using a pulpy newsprint paper and an efficient method of reproducing color called the four color process which used 64 colors mixed from four inks; yellow, cyan (blue), magenta (red) and black.
