Official color glossy 10 x 8 NASA photo from the personal collection of NASA technician Richard Underwood, who worked in the Johnson Space Center’s Photographic Technology Laboratory for over two decades. The photo shows astronaut Ed White performing his historic first American spacewalk during the Gemini 4 mission; visible in the far distance is southern California. Reverse bears “A Kodak Paper” watermarks. In fine condition, with trivial toning. Accompanied by a signed certificate of authenticity from Florian Noller of Artifact Cloud, and by a copy of the original certificate of authenticity from the Richard Underwood estate. Underwood was responsible for developing the Apollo photographs—in fact, he was the first person to view every photograph from the Gemini, Apollo, Skylab, Apollo-Soyuz, and the first 23 space shuttle missions.
