Bob Braverman helped invent the slot car, in 67 became the tech editor for the new magazine, Cycle Guide, then in '69, the editor and publisher, then started Street Rider and Custom Chopper magazines, and was inducted into the AMA Motorcycle Hall of Fame, and the National Motorcycle Museum Hall of Fame.

and supposedly, built this in 1969, and it's now on facebook marketplace for 20k. 

No, I don't think it's worth that, also, it's been listed there since March, the pieces were pulled out of storage in Nov 94
