Issued around 1904, this official Paraguayan stamp features the national emblem — a radiant star encircled by a laurel wreath — printed in a rich brown tone. The inscription “Unión Postal Universal” marks Paraguay’s membership in the international postal network. The overprint “Deficiente” (meaning “Deficient”) designates this as an official or provisional issue, often used when regular supplies were low. Such overprints make it a fascinating study piece for collectors of early 20th-century Latin American postal history.
