Sarednab makes one, but his take on it is that Indy is holding Abner's journal. It has Abner's notes about the Ark and is full of inserts, I would def. ask him about it if your interested.
It looks like the original has a khaki paper cover, while this one is brown like a brown paper bag, but at this price you can buy a couple and experiment with changing the color of the cover if you want.
