The Library of Congress has a new rolling exhibit that settled in Concord, NH in front of the state house. The exhibit, entitled "Gateway to Knowledge," contains reproductions of the Declaration of Independence, the first appearances of Spider-Man, the Gutenberg Bible, and others. The exhibit is currently on a 90 city tour and is free to the public.
Wow, that's quite a collection of fake artifacts. I am sure Marvel is excited to have their comics sitting next to the Declaration of Independence like that. Of course when I think historical documents, I go straight from Magna Carta to Superman, but that's just me.
Also, think about how jazzed Steve "The Gute" Gutenberg is that someone wrote a bible based on his storied career.
