US 1975 10c Apollo-Soyuz Stamps

A rare piece of Cold War cooperation on paper. The United States and the Soviet Union each issued stamps for their first joint space venture, the American pair going on sale on July 15, 1975, and the two artists split the story between them: Robert McCall painted the Apollo and Soyuz craft after link-up, and Soviet artist Anatoly Aksamit painted them before it. Mount the American pair beside the Soviet joint issue and the docking is told across two countries' stamps, which no other item here can do.
