In 1931, Diego Rivera (actually Diego María de la Concepción Juan Nepomuceno Estanislao de la Rivera y Barrientos Acosta y Rodríguez — whew, what a name!) painted The Making of a Fresco Showing the Building of a City at the San Francisco Art Institute. The mural is a meta-mural because it is a mural about murals and because it represents its creators in the act of creating the fresco itself.
Clarion Alley in the Mission District of San Francisco used to be a shady street where junkies would shoot up. In October 1992, a volunteer collective of residents organized the Clarion Alley Mural Project (CAMP) to bring art and color to the alley. The murals of Balmy Alley, which are focused on Central American struggle, inspired the project, but the murals of Clarion Alley are generally more playful and cartoon-like, although they deal with serious social issues as well (“What I Know is What I Owe,” said one mural and another challenged the “Demonocracy” of the United States–both of these are now painted over). Many murals explore the rich culture of the Mission, especially, of course, the predominate Latino culture.
