cool use of a bumper jack in a show car display... once you figure out how to keep it from falling over... maybe mount it to the back of a big stop sign?

Or even better, if you recall from years ago, the lexan/plexiglass signs that a car owner would use to hold an info sheet about the car, and it was about 4 foot high, and the foot of it was so long that the car would drive over it, and park on it, and then it couldn't be hit into the car? Something like that, but with this bumper jack mounted to it, holding an info sheet
