Bagley had so many awesome covers. Can anyone post a scan of #392 (Peter Parker no more?). That's one of my favorites. Not so much the actual story, but the cover itself is gorgeous and a great homage to the original Romita cover. And it only uses one color: red.
EDIT: Here it is.
I also love PP:SM #75 the final chapter of the clone saga with Pete and a bloodied Ben Reilly trying to fend off a crazed Norman. Man, what a classic.
