They have changed the email. The first one had December Z2, 2008 and it was a B&W copy.
Now this one says December 22, 2006
Man, I want this to be true, but points like this make me think otherwise.
Why would it have "Z2"? No one would make that kind of typo, since the "Z" and the "2" are quite far apart on the keyboard. Plus you'd have to shift to get that upper case "Z".
The fact that scan apparently distorted a "2" into a "Z" is further evidence that the apparent "2008" was and is really "2006".
