Whenever someone becomes famous, enterprising types come out of the woodwork to hawk various and sundry items once owned or used by the now well-known person.
Provenance, it's called. Just watch any episode of Antiques Roadshow, and you'll likely hear appraisers tell owners that their item is worth 'such and such' but if its provenance can be verified, the amount will be much more.
So when I saw this video, I wondered if it will someday end up on a Barrett-Jackson, Sotheby's, Christie's, or Ebay listing:
I guess it would be quite the step up from BHO's Chrysler 300.
...Or Bubba's El Camino with vintage DNA-encrusted astroturf bedliner.
