I'm guessing this was for a speed record attempt and the odd rear end on the Porsche was designed to reduce drag for the following cyclist. Note the nearly wheel-sized front sprocket shield.

I don't think the fork is bent. It looks like he flipped it around so he could suck in closer to the car. I'd sure hate to get my pants stuck in that sprocket.

Things are easy to find when you know the right keywords.
This is from Jean Claude Rude's speed record attempt in 1979. That is the chainring, not the guard. The Porsche was driven by former F1 driver Henri Pescarolo. The bike's rear tire exploded at at 105mph. Rude was unhurt, but he wasn't able to break the world record.
As for the fork, it was assembled that way at the department store.

The act of bicycle pacing behind a motor vehicle is traditionally called "staying". The bicyles are refered to as "stayers" and have steep head angles, smaller front wheels and reverse rake forks to allow the cyclist to be closer to the motor vehicle for a better draft. The negative rake actually restores trail lost due to the smaller wheel and steeper head tube.

The "reversed" fork adds trail to the frame geometry, which adds stability at speed.
... but I do like the "department store" reason.

I believe that's Pescarolo on the right. He never won a Formula 1 race, but did win Le Mans 4 times.
