Souvenir treaty entitled “Agreement on the Rescue of Astronauts, the Return of Astronauts and the Return of Objects Launched into Outer Space,” on a 16.5 x 10.25 sheet of parchment-type paper, signed in blue and black ink by Dean Rusk, Patrick Dean, and the Russian representative. Treaty also bears an August 2, 1971 Kennedy Space Center postal cancellation, a First Day of Issue stamp, and two eight-cent postage stamps. In fine condition, with a central vertical fold and a small pencil notation to bottom edge. Also referred to as the ‘Rescue Agreement,’ it is an international agreement setting forth rights and obligations of states concerning the rescue of persons in space. The Agreement was created by a 1967 consensus vote in the United Nations General Assembly; it came into force in 1968. These scarce souvenirs were produced by longtime autograph dealer Sy Kessler to commemorate this event. RRAuction COA.
