Caption: "Obregon's tomb, Mexico City." William and Grace McCarthy standing before the monument to General Alvaro Obregon (1880-1928), who was a leader of the Mexican Revolution (1920-1920). Obregon was elected President of post-Revolution Mexico, serving from 1920-1924. In 1928, he was again elected but was assassinated by Jose de Leon Toral, a Roman Catholic who opposed Obregon's policies on religious matters. The monument was completed in 1935 and stands in the San Angel region of Mexico City, in the same location where Obregon was assassinated.
