Sonora, Mexico Provisional 'Coach Seal' Issues
Mexico · 1913 · Various
This stamp is part of the 'Coach Seal' series, a provisional issue from the state of Sonora during the Mexican Revolution. The design features a simple stagecoach, representing the traditional method of transport, and was locally produced due to the disruption of federal postal services. These stamps exist in numerous varieties of color, paper, and perforation, making them a complex area for specialists.
Issued by the Constitutionalist forces under Venustiano Carranza in Sonora, these provisional stamps were a necessity during the Mexican Revolution (1910-1920) when revolutionary-held territories operated their own postal systems.
