On January 27, 1967, the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, was signed by the United States of America, the United Kingdom, and the Soviet Union. Since then, over 100 countries have signed and/or ratified the treaty (more informally known as the Outer Space Treaty), agreeing that the earthly conflicts occasionally entered into among nations (ahem) should remain global, not universal. Here’s hoping that continues! These stamps celebrate a US-Soviet cooperative effort in 1975, bringing the Apollo and Soyuz modules docked together for two days in space, the first such international collaboration beyond the globe. Much like the Outer Space Treaty was an international non-partisan effort to rise above the political squabbles, the postal systems worldwide have more often than not engaged in cooperation and reciprocation at times when conflicts have otherwise stagnated international relations. At a time when the Cold War was still flaring, these stamps were jointly issued by the USPS and the Soviet Post. Way to keep it real, Universal Postal Union.
