When you read the entire Harry Osborn arc in one go, certain things jump out at you. One of my favourite details is this: on three occasions (gotta love the rule of three), Harry is driven away leaving Peter alone in the road at the end of the story.
First, in Amazing Spider-Man #137:
Second, in Spectacular Spider-Man #189:
And thirdly/lastly, in Spectacular Spider-Man #200:
That time, of course, it’s the real end.
God, don’t you just love the juxtaposition of these two panels? No way Sal Buscema didn’t do that on purpose.
