1968 Super Bee convertible show car

I was scanning back issues of my magazine collection, and in the Dec/Jan 1991 issue of Mopar Muscle, I came across a picture of a 1968 Super Bee convertible show car. I scanned the picture and posted it below. I can't remember ever seeing the car before, and I have never read anythin about it. Can anybody give me some history on this car? I think the hood blackout treatment is really cool. Check out the side pipes! Does this car still exist today?
