This 8x10 NASA photo is signed by Joe Walker in black felt tip pen. The photo is mounted to an album page with a signed photo of Abubakar Tafawa on the back. The Walker signature is pre-certified by BAS, but the signature on the back was ruled unable to render and opinion. Joseph A. Walker (1921-1966) was an American World War II pilot, experimental physicist, NASA test pilot, and astronaut. He was one of twelve pilots who flew the North American X-15, an experimental space plane jointly operated by the Air Force and NASA. In 1963 Walker made three flights above 50 miles, thereby qualifying as an astronaut according to the United States definition of the boundary of space. The latter two, X-15 Flights 90 and 91, also surpassed the Kármán line, the internationally accepted boundary of 100 kilometers (62.14 miles). Making the latter flights immediately after the completion of the Mercury and Vostok programs, Walker became the first person to fly to space twice. He was the only X-15 pilot to fly above 100 km during the program. Walker was killed on June 8, 1966, when his F-104 Starfighter chase aircraft collided with a North American XB-70 Valkyrie. His autograph is rare.
