The stamps have the Mexico overprint, except perhaps for the first period stamps, none of which are known to exist today.
Only four copies are known to exist: two copies of the 2R 63-1866 cancelled in Rio Frio, one 1R without name cancelled in Rio Frio and one from the Mexico consignment 78-1866 with a Rio Frio cancel. It is quite possible that the latter was brought from Mexico and used in Rio Frio, since Rio Frio was a stop on the diligencias route.
It is generally believed that the small "districts" of Guadalupe Hidalgo, Lerma, Rio Frio, San Angel, Tacubaya, Texcoco and Tlalpam were actually sub-offices of Mexico.
