A totally unknown (to most people, anyhow) pre-Spawn Todd McFarlane.
His true story was that had drawn (at the time, it may still be, I don't really follow comics anymore) the biggest selling issue of Amazing Spider-Man to date.
The kicker is, a year after this appearance, he would form Image Comics, start publishing Spawn, parlay that into a massive multimedia empire, and today has more money than God.
(His fake story, by the way, was that he was a cab driver who gave someone a ride home to New York from Vegas at the cost of $10,000.)
