Normally, we politely but clearly decline accepting catalogs and promotional books at game conventions. (They quickly add up.) But when someone hands you a Metal Gear promo item, you'd be a fool to leave it in a booth companion's hands.
Kojima Productions knows how to put together some informative literature, as you might be able to gather from perusing the TGS Metal Gear Solid: Peace Walker promo book yourself. It's brief, but big—about 14" by 10" when folded. Plus, it's pretty too look at, with snazzy artwork from Metal Gear maestro Yoji Shinkawa and good design slathered all over the thing.
Take a peek. And be gentle with the quality. The Japanese authorities confiscated my scanner at customs.
