There is actually a book on it. I have it. Its really great. Has every single G1 figure ever released. Has a great amount of pics, and prices from ML, MIB, MISB, shows all the accessories, has info, character bio's, heaps of really great info. It cost me $40 AUD, and its called "TRANSFORMERS: Indentifcation and Price Guide"
