I had one of these as a kid, wish I wouldn't have thrown it away. The developers came to my elementary school in Spokane and gave all the kids free copies of the game and random stuff like this mouse pad. If you don't own one, don't miss out.
No Myst collection is complete so long as your mouse's roller ball is moving on bare desk.
This official mousepad measures 9.25 by 7.75 inches and is made from soft woven polyester bonded to a rubber base.
