The Spectacular Spider-Man #33

This 1979 Marvel entry finds Spider-Man in a genuinely harrowing predicament — the cover by Al Milgrom shows the wall-crawler engulfed by a massive constricting serpent while a writhing mass of reptilian creatures snaps and claws at him from below, the tagline "…Of Spiders and Snakes!" perfectly setting the tone. The composition pulls you right into the chaos, with Spidey's masked face visible beneath the coils as the sea of scaly bodies threatens to overwhelm him entirely. Bill Mantlo's script paired with Jim Mooney's interior art promises the kind of pulse-quickening adventure that made Spectacular Spider-Man such a compelling companion title in the late Bronze Age.
