For those that don't know, the villains are: Man-Wolf, Punisher, Morbius, Green Goblin, Stegron, Lizard, Dracula, Mysterio and the Jackal...but you knew that, right?
Still, Perez did do a couple of covers for Peter Parker, the Spectacular Spider-Man (#9 and #10, August/September 1977), when Peter teamed up with the White Tiger, inked by Frank Giacoia!
While not issues of Amazing Spider-Man, George did do three issues of Marvel Tales, featuring reprints with Spider-Man facing the Hobgoblin (#259 - #261 in 1992, George also inked covers for a mini-series featuring the Hobgoblin, but we'll cover those later!).
Just because it fit with the October/Halloween them, included a cover of Spider-Man Team Up (#4 in September, 1996), with Spidey and the Avengers, because George was better known for his Avengers work.
