Issued in 1955, this 20 centavos airmail stamp from Guatemala commemorates the “Liberación de 1954–1955,” celebrating the fall of the communist government following the CIA-backed coup that ousted President Jacobo Árbenz. The design depicts the Monument to the Martyrs of Anti-Communism, with Guatemala’s national flag waving beside the memorial obelisk and the symbolic dagger emblem. Printed by Staatsdruckerei Wien (Vienna State Printing Works), this stamp is both a historical artifact of Cold War politics and a striking example of Guatemalan commemorative postal design.
