A finely engraved 40 centavos commemorative from Chile, issued in 1958 to mark the 100th anniversary of the Instituto Alemán Carlos Anwandter in Valdivia (1858–1958). The design features a graceful sailboat on the Calle-Calle River with the iconic Pedro de Valdivia Bridge, rendered in crisp green tones. Produced by the Casa de Moneda de Chile, the stamp showcases classic mid-20th-century Chilean engraving with sharp lines and excellent depth. An attractive thematic item for collectors of bridges, sailing, architecture, and Chilean commemoratives.
