I'm not a fan of G.I. Joe, a line of toy soldiers made famous in the 80s, but even I'm impressed with this dude's work, The Complete Guide to G.I. Joe: A Real American Hero. It contains information on each of the 700 US-released G.I. Joe figures along with pictures, description of appearance and accessories, filecard information, and notes on their release and other notable facts. And that's not all.
