"Return of the Black Flame" kicks off in Adventure Comics #400 (1970), a milestone issue marked by a dynamic cover by Mike Sekowsky and Dick Giordano that captures the era’s bold artistic energy. This issue stands out not just for its story, but as a snapshot of 1970s comics culture, featuring a report on the Comic Art Convention in New York City where Carmine Infantino, Joe Kubert, Dick Giordano, and Neal Adams were honored with awards—highlighting the industry’s appreciation for their craft, as seen in uncredited portraits of the celebrated artists.
