This classic Paraguayan stamp features the portrait of President Juan Gualberto González, printed in deep blue and originally issued around the turn of the 20th century. The design includes ornate framing and the inscription “UNION POSTAL UNIVERSAL” along the sides, marking Paraguay’s participation in the Universal Postal Union. This particular example bears the black overprint “Habilitado 1903”, signifying its official revalidation for postal use during that year—a common practice in Paraguay’s early philatelic history. A distinguished and highly collectible item for specialists in South American and overprinted issues.
