Issued by Correos de Chile in 1969, this striking 3 Escudos commemorative stamp honors Chile’s participation in Expo ’70, held in Osaka, Japan. The minimalist design features the official Expo emblem — a stylized flower symbolizing harmony and progress — printed in white against a deep blue field. Produced by the Casa de Moneda de Chile, the stamp reflects Chile’s spirit of international cooperation and technological optimism during the late 1960s. A classic example of modernist philatelic design linking South America to a major global exposition.
