This is the letter handed to the Doctor Bravestone by Nigel Billingsley when he picks them up in the car. The letter is used to set the backstory of the game. Unlike other letters in the marketplace, this letter has considerable wear and has a piece of the script taped inside which matches the dialogue spoken by Dwayne Johnson. While I have not been successful in screen matching this item, I believe it was the one used in the movie, rather than a backup.
