This commemorative airmail stamp from Colombia celebrates the 50th anniversary (1919–1969) of Avianca, one of the oldest airlines in the world. The design prominently features a golden anniversary medallion with the Avianca logo, alongside a classic mid-20th century aircraft in flight. The green emblem marking “Correo Aéreo” (Airmail) further emphasizes its postal aviation significance. The airmail-themed border styled like an envelope adds a distinctive visual appeal. Printed by De La Rue, this issue is a notable piece for collectors of aviation and airline history.
