Issued in 1976, this 6 centavos commemorative stamp from the Dominican Republic celebrates the 50th anniversary of the Radio Club Dominicano, Inc. (1926–1976). The design, rendered in bold red and white, features symbols of communication — a radio antenna, atomic motif, and sound waves — alongside the club’s emblem (RCD). The inscription “Los radioaficionados fomentan la fraternidad universal” (“Radio amateurs promote universal brotherhood”) highlights the global unity fostered through amateur radio. A fitting tribute to half a century of technical progress and international friendship.
