Impressive collection of 23 official NASA photographs of concept artwork for the Space Shuttle program and its Orbiter Spacecraft and Shuttle Carrier Aircraft, ranging in size from 10 x 8 to 20 x 16, with five photos affixed to cardstock mounts (includes some red-numbered variants). The majority of photos feature “A Kodak Paper” watermarks on the reverse. In overall very good to fine condition. From the personal collection of Paul Kruppenbacher, a member of the NASA Houston Landing and Recovery Division who trained Apollo astronauts in water recovery procedures and was deployed on U.S. Navy aircraft carriers for crew and spacecraft recovery operations.
