A classic late-19th century definitive from El Salvador, featuring a finely engraved allegorical female figure symbolizing Liberty and national strength, framed within ornate Victorian-style scrollwork. The bold “SERVICIO POSTAL DEL SALVADOR” and large numeral “3” create strong visual appeal typical of early Latin American issues. Printed in a warm yellow-orange shade, this 1890 issue reflects the elegant typography and craftsmanship of the period. A highly collectible foundational stamp for El Salvador country collections, classics albums, and thematic displays on allegory or classical figures. Scarcer in clean, well-perforated condition, making attractive examples especially desirable.
