The San Quentin Murals, painted by Alfredo Santos, depict the history of California through the eyes of an inmate. The murals were created over 50 years ago by then inmate, Alfredo, who was serving a 4 year sentence for the possession of heroin. Alfredo submitted a sketch in a competition among inmates to paint a mural in the dining hall. After completion of the above mural, Alfredo went on to paint 5 other murals, in the course of 2 years, each measuring 12 feet high by 100 feet wide. These murals show art and crime together by exposing the artistic talent of a man who was serving time for a criminal act.
