Space Cover Signed by Valery Bykovsky Soviet Cosmonaut  Pilot

8 12 83 Mockba Russian Space Cover Personally Signed by Valery Fyodorovich Bykovsky . Who was born 2 August 1934, Pavlovsky Posad. He is a retired Soviet cosmonaut who flew three manned space mission space flights: Vostok 5, Soyuz 22, and Soyuz 31. He was also backup for Vostok 3 and Soyuz 37.
Bykovsky set a space endurance record when he spent five days in orbit aboard Vostok 5 in 1963. Although this flight duration has long since been surpassed by crews of more than one person, to this day it remains the endurance record for a solo spaceflight.
 Bykovsky was to have commanded the original Soyuz 2 mission, which was cancelled due to problems with Soyuz 1. After the parachutes failed on that mission, killing Vladimir Komarov, the same problem was found with the Soyuz 2 capsule, which meant if the mission had flown, Bykovsky and his crew would also have been killed.Details enclosed
