Issued in 1977, this Bolivian commemorative stamp honors the 50th anniversary of radio broadcasting in the country (1927–1977). The design by A. Bel features a bold orange silhouette of Bolivia, overlaid with radio transmission towers radiating signals across the nation — symbolizing the unifying power of communication. The banner above reads “Homenaje a la Radiodifusión Ital” (“Tribute to Broadcasting”). Issued by Correos de Bolivia with a denomination of Bs 2.50, it celebrates ASBORA (Asociación Boliviana de Radiodifusión) and the pivotal role of radio in national development.
