Kunzle outlines the historical conditions in Nicaragua that gave rise to the Revolution and to the murals, from the era of Sandino and the Somozas to the Sandinistas and the subsequent U.S.-supported contra war. He chronicles the politically vindictive destruction of many of the best murals and the rise and fall of Managua's Mural School, a unique institution in the world. Kunzle also refers to other Nicaraguan public media such as billboards and graffiti, the great mural precedent in Mexico, and the attempts at socialist art in revolutionary Cuba and Chile.
