This is a Mexican fiscal (revenue) stamp issued in 1908 for the "Control del Talon" system, used to regulate patents, direct contracts, and guides. It has a face value of 50 Pesos and was printed in a blue design featuring ornate lettering with a bold control number at the top. The text indicates that this portion of the talon remained in the Oficina Recaudadora (Revenue Collection Office) as proof of payment. Such high-denomination fiscal stamps were essential for large commercial or legal transactions in early 20th-century Mexico. Its large format, serial number, and specialized usage make it a prized collectible for revenue stamp enthusiasts.
