This 1 Peso brown stamp from Paraguay features the national star emblem surrounded by a radiant sunburst and laurel wreath, representing honor and unity. Inscribed “República del Paraguay” and “Unión Postal Universal”, it marks Paraguay’s adherence to the Universal Postal Union standards. The overprint “DEFICIENTE” (meaning “deficient”) was used on revalidated or lower-quality official issues—an interesting postal marking for collectors of specialized errors or administrative usages. A fine example of early 20th-century Paraguayan official postal practices.
