Justice League America #30

That grinning close-up face — sunglasses reflecting a startled Mister Miracle, the Huntress, and what appears to be a green-hued figure amid chaotic surroundings — makes for one of the more memorably unnerving covers of 1989, rendered with sharp wit by Kevin Maguire and Joe Rubinstein. The smirking mystery figure dominates the composition, while the heroes caught in those mirrored lenses look genuinely alarmed, perfectly setting the tone for a story titled "Teenage Biker Mega-Death!" The Giffen and DeMatteis era was reliably entertaining, and this issue's cover alone promises the blend of humor and genuine tension that made Justice League America such a fun read.
