GRAPHIC NOVELS - DC COMICS - SUPERMAN

Superman was created by writer Jerry Siegel and artist Joe Shuster, and first appeared in Action Comics #1, a comic book published on April 18, 1938. 

Although Superman was not the first superhero character, he popularized the superhero archetype and defined its conventions. Superheroes are usually judged by how closely they resemble the standard established by Superman. He was the best-selling superhero character in American comic books up until the 1980s.
