Motorcycle daredevil (1938-2007) who brought showmanship to the sport in the 1970s. He often chose a surprisingly difficult obstacle (such as the fountains at Caesar's Palace in Las Vegas in 1968, or a row of 13 double-decker buses at London's Wembley Stadium in 1975). Dressed in his red, white and blue jumpsuit, Knievel would race his motorcycle up a specially-constructed ramp and leap over the obstacle. He often crash-landed, thrilling viewers while breaking dozens of bones. In 1974 he arranged his most famous stunt, an attempted jump over Idaho's Snake River Canyon in a rocket-powered motorcycle. The attempt failed when the craft's parachute opened prematurely, but Knievel survived. He retired in 1981. One dozen official Rawlings Major League baseballs, each signed on the sweet spot in ballpoint by Knievel. In very fine condition. R&R COA.
