Is this tomorrow - A cover of a comic book with a picture of a man on fire

The Golden Age of Comic Books was a period in the history of American comic books, generally thought of as lasting from the late 1930s until the late 1940s or early 1950s. 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 Superman, Batman, Captain America, Wonder Woman, and Captain Marvel. The publishing of comic books became a major industry. The period also saw the emergence 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.
