Issued in 1949 by Correos de Chile, this striking $2 airmail stamp commemorates the 20th anniversary of Chile’s national airline, Línea Aérea Nacional (LAN), founded in 1929. The design features the LAN emblem within a compass rose, flanked by banners inscribed “1929–1949,” symbolizing two decades of aviation progress. Several aircraft silhouettes in flight emphasize Chile’s modern air connections during the mid-20th century. Printed in a rich blue shade, this stamp represents both postal history and the development of commercial aviation in South America. A must-have for collectors of airline and Latin American issues, it embodies a key milestone in Chile’s aerophilatelic heritage.
