Issued in 1894 under the “Ley de Sellos de la Provincia de Buenos Aires,” this 0.50 centavos provincial revenue stamp was used for the “Guía de Campaña” — documents certifying the transport of livestock and goods. The design features a detailed engraving of a ram’s head within an ornate frame, symbolizing Argentina’s strong pastoral economy. Printed in rich violet with a serial number in red, each stamp was individually numbered to prevent forgery and track official use. A fine example of Argentina’s 19th-century fiscal philately, prized for its intricate design and historical context.
