Golden Age of Comic Books
From The Art and Popular Culture Encyclopedia
The Golden Age of Comic Books was a period in the history of American comic books, generally thought as lasting from the late 1930s until late 1940s. During this time, modern comic books were first published and enjoyed a surge of popularity; the archetype of the superhero was created and defined; and many of the most famous superheroes debuted, among them Batman, Captain America, Superman, and Wonder Woman.
The period saw the arrival of the comic book as a mainstream art form, and the defining of the medium's artistic vocabulary and creative conventions by its first generation of writers, artists, and editors.
