Issued by Togo in 1975, this vibrant two-stamp airmail set commemorates the historic Apollo–Soyuz Test Project, the first joint U.S.–Soviet space mission symbolizing Cold War détente. The 100F stamp features the docked Apollo and Soyuz spacecraft with the American and Soviet flags waving above, set against a green cosmic background. The 200F airmail stamp displays the official mission emblem alongside Earth, emphasizing international cooperation in space exploration. Bright colors, strong space theme appeal, and Cold War historical significance make this set highly desirable among thematic collectors of space, aviation, and international relations philately.
