GEORGI DOBROVOLSKY AND VIKTOR PATSAYEV An excessively rare signed Soviet space item, a 1968 Soviet space flight commemorative postcard signed by cosmonauts GEORGI DOBROVOLSKY and VIKTOR PATSAYEV (in block letters), and dated by each June 6, 1971, the day they took their fateful flight! The lives of these two cosmonauts, along with that of Vladislav Volkov, were lost on the flight of Soyuz 11. Following a four-week stint aboard the Salyut space station, all three perished when their craft lost its pressurization upon re-entry to Earth's atmosphere. An exceptionally rare item, with the best date possible! Fine condition. $1,500-2,000
