Issued by Correos de Chile in 1960, this 20 centavos commemorative stamp marks the 150th anniversary of Chile’s First National Government of 1810. It features portraits of Manuel de Salas and Juan Egaña, two important figures in Chile’s early independence movement. Printed by the Casa de Moneda de Chile, the design uses a detailed line-engraved style in blue-green, with strong ornamental framing. This issue is part of the series celebrating Chile’s path to independence and remains a historically significant piece for collectors of Latin American philately.
