This is a 1908 Mexican fiscal (revenue) stamp denominated 1 Peso, issued for the Control del Talon system. The stamp was used for patents, direct contracts, and shipping guides, with the instruction that the stub remained in the tax office (Que queda en la Oficina Recaudadora). It is printed in blue on white paper with a bold serial number at the top, serving both fiscal and control purposes. These stamps were not for postal use but were vital in documenting official financial transactions during the Porfirio Díaz era. A collectible piece of Mexico’s complex revenue system.
