Michael Chabon's "Spiderman II" script unearthed

Not sure if there are many Chabon fans here, or Spiderman ones for that matter, but some of you may be interested to know that McSweeney's has apparently released Michael Chabon's unused "Spiderman II" script. It's available for perusal in PDF here.I make no claims regarding the script's authenticity, but as it is being released via McSweeney's Internet Tendency in conjunction with the debut of Chabon's Maps and Legends I suspect it is legitimate.
