The Spectacular Spider-Man #31

Spider-Man finds himself in a tight spot on the cover of this June 1979 Marvel issue, grappling with the massive, spotted green coils of what appears to be a giant serpentine creature amid an industrial backdrop of machinery and equipment. The cover art by Al Milgrom and Klaus Janson delivers a visceral sense of scale and danger, with Spidey straining against the creature's bulk while a collar of some kind encircles his neck. With a story titled "Till Death Do Us Part!" and the interior team of Bill Mantlo and Jim Mooney at the helm, this one promises the kind of high-stakes adventure that made Spectacular a fan favorite throughout the late Bronze Age.
