Lud Denny auto on 1990 Pro Set Andre Rison card is upside down
 

I present to you this evidence, now that I have received a Ludwell Denny autograph of my own.

We know the 1990 Pro Set Andre Rison fiasco (or a "who would have noticed?" situation) where they didn't put a traded stripe on the Andre Rison card from series 1. So they then made an apology card in (Series 2 and?) the Final Update set with this "Are you missing something" text on the back and a fascimile Ludwell Denny autograph present.

I had recently become aware of another place one of his fascimile autographs was present on (it is slightly different) and that is the 1991 Pro Set Desert Storm factory set. As it turns out, there is a Limited Edition factory set with his actual autograph on it. That is how I noticed the fascimile autos on the factory set and the Andre Rison card are actually upside down.
