The collection consists of photographs from the Mexican Revolution (1910-1920) taken by Agustín Victor Casasola, a Mexican photographer and co-founder of the Mexican Association of Press Photographers. Photographs in the collection also include depictions of daily life in Mexico, and Mexican presidents in the early 20th century. In addition to photographs taken by Casasola, there are additional photographs on Mexico and its politics taken by Casasola's sons after his death in 1938.
