From Star Wars swag and Civil War cannons to fossils and rare paintings, the expert art dealers on Discovery’s Final Offer have seen some unusual items. And when gallery owner Patrick Painter, our guest tonight, was presented with a valuable and unique piece of modern history, he did the right thing.

Expect the unexpected tonight when Patrick Painter discusses the Discovery channel program Final Offer, the current state of art and collecting in America, and James Earl Ray’s 1967 prison escape map which Painter bought on the show and donated to the King Library and Archives in Atlanta, part of the King Center for Non-Violent Social Change.
