Ace Harlem is the detective lead of All-Negro Comics. He was created in 1937 by Orrin C. Evans and appeared in the Pittsburgh Courier newspaper in at least 30 strips. The story in All-Negro 01 is a reprint of one of these. The comic book company All-Negro Comics was the first publisher that consisted solely of Afro-American creators and heroes. Ace Harlem was not a superhero, but is one (if not the first) heroic black comic character. Unfortunately, only 1 issue of the comic-series was printed, even though issue 1 announced a second issue with another adventure of Ace Harlem.
