It comes in a sweet rough-style paper with a great smell.

The outside is sealed with a sticker on the back that reads:

A history and portait of the MGS series.
Pictures of MGS3 and the latest secret game and character info.
A background of the era that MGS3 takes place in.
Missions details and a review to help you decode MGS3's secrets.
On-location research photos and a conversation with Director Hideo Kojima.
Helpful information related to the mission's objectives.
There are approximately two months remaining until FOX's sure-to-be memorable inaugural mission. Please use this to prepare for that day, and look forward to perfection.

FOX"
I'm guessing FOX is the name of the covert operations body in MGS3... Damn, something else I didn't want to know.
Sorry if you want info on the contents, but I'm trying to avoid spoilers. I opened up the first page and there was the main character with his sniper rifle wearing the alligator crown, so that was enough for me.

BTW, it says that The Art of Metal Gear Solid 3 is due out in late March.
Edit: Okay, holy shit, I looked at the back of the book at the research photos.... This game is gonna be AMAZING!
