 The first modern comic books under the Marvel Comics brand were the science-fiction anthology "Journey into Mystery" #69 and the teen-humor title "Patsy Walker" #95 (both cover dated June 1961), which each displayed an "MC" box on its cover.Then, in the wake of DC Comics' success in reviving superheroes in the late 1950s and early 1960s, particularly with the Flash, Green Lantern, Batman, Superman, Wonder Woman, Green Arrow and other members of the team the Justice League of America, Marvel followed suit.In 1961, writer-editor Stan Lee revolutionized superhero comics by introducing superheroes designed to appeal to older readers than the predominantly child audiences of the medium, thus ushering what Marvel later called the Marvel Age of Comics.
