Founded in Prague in 1946, the International Union of Students (IUS) sought to create a global alliance of student organizations focusing on issues of human rights, access to education, and the defense of peace. While originally nonpolitical, the organization was quickly dominated by Communist student groups in governing positions, leading to the withdrawal of groups from Western Europe. This poster, published by the IUS, was issued in English, Spanish, and French, and distributed to Communist-aligned student groups around the world. It is one of many antinuclear designs produced by the IUS between the 1960s and the 1980s. Regardless of political affiliation or country of origin, young people who grew up in the 1950s and ‘60s all lived under the daily threat of nuclear holocaust. It was common for them to experience drills at school in which they were instructed to “duck and cover” under their desks for protection. In some parts of the United States, children were given dog tags so that, in the event of a nuclear attack, their parents could identify their bodies.
