So this may be a little out of the expertise here but I figured I would ask - tried the normal lot of internet scavenging and cannot find an idea of if this is worth anything. It seems to be a neat book that went along with the game, I'm not sure it was packaged with the game because I don't see it in alot if the pictures of the people claiming to have a complete box of this. It has this neat piece of red transparent and the secrets are actually overlaid so you need this to read most of the book.
