5c orange postal stationery envelope with 'VILLA - ZAPATA' monogram overprint in black (UPSS #E71aB-3, H&G IB10) used with MERIDA YUCATAN cds dated 26 SEP 1915. Addressed to FRANCE, correctly taxed with boxed 'T 5 CS' in blue as the Civil War overprinted envelopes were not valid for use outside of Mexico. PROGRESO transit cds on reverse. Very scarce.
