The Spectacular Spider-Man #27

Spider-Man and Daredevil team up in this 1979 Marvel gem, brought together under the ominous title "The Blind Leading the Blind." Dave Cockrum's pencils and Al Milgrom's inks deliver a striking cover bathed in swirling red, where a disoriented Spider-Man cries out that he's been struck blind — leaving Daredevil, himself no stranger to darkness, as the duo's unlikely guide against an unseen threat represented by the massive weapon barrel looming in the foreground. With interior art by a young Frank Miller and script by Bill Mantlo, this issue pairs two of Marvel's most compelling street-level heroes at a genuinely tense moment.
