This Chilean commemorative, issued in 1982, honors the 1980 Political Constitution alongside a portrait of Diego Portales, a key 19th-century statesman whose ideas shaped the nation's institutional development. The design features Portales at left and the Chilean national coat of arms at right, accompanied by the constitutional maxim: “El Estado está al servicio de la persona humana y su finalidad es promover el bien común.” Printed by the Casa de Moneda de Chile, the stamp reflects a period of significant constitutional transformation in the country. Its clean layout and strong political theme make it an appealing addition for collectors of Latin American history, political philately, and statesmen-themed issues.
