This is a Mexican revenue stamp issued in 1908, denominated at 6 Pesos. The design bears the inscription “CONTROL DEL TALON AÑO 1908 – Patentes, Cont. Directa y Guías”, indicating its use for patents, direct contracts, and guides, serving as a receipt control stub. Printed in blue with bold black serial number 016722, it was intended to remain on file at the revenue office (“Que queda en la oficina recaudadora”). Such fiscal issues are prized for their historical connection to Mexico’s early 20th-century taxation and administrative system.
