Brigada Alvarez

Herminio Alvarez was a Constitutionalist general in the forces of Luis Gutiérrez, who operated in Coahuila, San Luis Potosí and Zacatecas. He fought the Villistas in the north of his home state, San Luis Potosí. He captured the city of San Luis Potosí on 16 July and, on his own iniciative, asumed power, handing over on 18 July to Gabriel Gavira, who was named governor by Álvaro Obregón.

On 5 February 1915 at Matehuala the Brigada Alvarez of the División del Centro, issued $1, $5 and $10 notes. These were authorized by Alvarez as governor of the state and carried his signature and that of the Jefe de Hacienda, C. Vaca.

The notes were to be exchanged at par for the currency that Carranza was about to issue.
 
The reference would be to Carranza’s Gobierno Provisional de México notes issued in Veracruz in February 1915.
