Oh happy day!!! I've been hunting this one for a while. Only 107 in 9.8 of this one (fewer than others around this time) and it's got WP too. Tough black / dark cover. I love the yellow story title popping off the background and the bad guys coming at you. And one of the reasons this is a grail for me and my Hobgoblin collection, is that it has BOTH the Hobgoblin and the Jack O'Lantern on the cover! I'm pretty sure this is the only time these two shared a cover in their original monikers. And here's another one, Ned Leeds is in it too! Oh - and you've got Hammerhead, Rose, and the Punisher making appearances as well. So much going on, Spidey didn't even make the cover in his own book!
So, here she is... Amazing Spider-Man #284:
