@Hornacek – P.S. – This might sound crazy, considering how popular and oft-referenced it is, but I completely forgot about that particular cover.
@Hornacek – I thought that was so stupid.
Of course. McFarlane’s SM #1 has “THE LEGEND OF THE ARACHKNIGHT” written on it.
@Hornacek — Remember the days of the “Arach-knight”? Not the Spider-man / Moon Knight amalgamation, but the Todd McFarlane’s darker Spider-man?
This scene looks like Spidey should be saying “Swear to me!”
