Appealing group lot of 15 official color glossy 10 x 8 red-numbered NASA photos deriving from the personal collection of astronaut Deke Slayton, with each photo showing uncommon images from the Apollo-Soyuz Test Project, which involved the docking of an Apollo Command/Service Module and the Soviet Soyuz 19 capsule, an historic event that marked the conclusion of the Space Race. Images include: a view of Massachusetts and Cape Cod as seen from space; the Soyuz 19 floating high above Earth, as viewed from the Apollo CSM; Flight engineer Valeri Kubasov holding up a certificate; Kubasov and Commander Alexei Leonov floating in their capsule; Slayton floating and wearing a ‘Snoopy’ cap; and various other images of the crew in space. Reverse of each photo bears “This Paper Manufactured by Kodak” watermarks and a stamp indicating that it originates from the “‘Deke’ Slayton Estate Collection.” In overall fine to very fine condition.
