At the dawn of the American comic book industry comic book packagers were starving for content. Anyone who could hold a pencil could get a job making comics. One of the strangest and darknest voices in this era was Fletcher Hanks.
He worked for a variety of publications, including "Fantastic Comics", "Fight Comics", "Jungle Comics" and many many more, creating such characters as Stardust the Super-Wizard and Fantomah. Soon, these publications fell into obscurity and were long forgotten.
In the early days of the twenty-first century his work was rediscovered, appreciated more for his strange sense of storytelling and anatomy than his storytelling ability. And the companies he'd worked for could not care less about copyright, so pretty much his entire backlist is in the public domain.
Since then these comics have been widely republished, both all over the internet and in various print publications, including "I Shall Destroy All the Civilized Planets" and "You Shall Die by Your Own Evil Creation", edited by Paul Karasik and published by Fantagraphics.
