Depicts the seal of the United Mexican States.

The Seal of the United Mexican States is a modified version of the national coat of arms, with the addition of the full official name of the country Estados Unidos Mexicanos, in a semi-circular accommodation in the upper part of the seal. Current and past Mexican peso coinage have had the seal engraved on the obverse of all denominations.

The coat of arms depicts a Mexican golden eagle perched on a prickly pear cactus devouring a rattlesnake. To the people of Tenochtitlan this would have strong religious connotations, but to the Europeans, it would come to symbolize the triumph of good over evil (with the snake sometimes representative of the serpent in the Garden of Eden).

Francisco Villa (1876-1923) was a Mexican Revolutionary general and one of the most prominent figures of the Mexican Revolution.

When Madero's revolt broke out, Francisco Villa joined the revolutionary contingent thanks to the intervention of Abraham González. In a short while, Villa stood out for his military talents and his knowledge of the terrain, obtained during his years as a cattle thief. He raised the most important military force of the Revolution: the Northern Division, which took Zacatecas, among other feats, a city that was a hub for the federal army, and with that victory, defeated the army of Victoriano Huerta. The sense of social justice in Villa's cause, evident during his governorship of Chihuahua, ended up putting him against Constitutionalism.
