This top view photo (I stole from Ned) really gives a good view of the shape of Mark's board. The Assault Heintzman is 9.625" wide by 32" long with a dual wheelbase of 14.25" or 15". Buy one! It's made in America and the graphics are not a heat transfer.
This would look good on your wall, but even better with trucks and wheels. That's why I recommend you buy two of them because you're going to want to set it up and ride it.
