Book excerpt: Superhero comic books are traditionally thought to have two distinct periods, two major waves of creativity: the Golden Age and the Silver Age. In simple terms, the Golden Age was the birth of the superhero proper out of the pulp novel characters of the early 1930s, and was primarily associated with the DC Comics Group. Superman, Batman, Green Lantern, and Wonder Woman are the most famous creations of this period. In the early 1960s, Marvel Comics launched a completely new line of heroes, the primary figures of the Silver Age: the Fantastic Four, Spider-Man, the Incredible Hulk, the X-Men, the Avengers, Iron Man, and Daredevil. In this book, Geoff Klock presents a study of the Third Movement of superhero comic books. He avoids, at all costs, the temptation to refer to this movement as "Postmodern," "Deconstructionist," or something equally tedious. Analyzing the works of Frank Miller, Alan Moore, Warren Ellis, and Grant Morrison among others, and taking his cue from Harold Bloom, Klock unearths the birth of self-consciousness in the superhero narrative and guides us through an intricate world of traditions, influences, nostalgia and innovations - a world where comic books do indeed become literature.
