And a dedication ceremony takes place today for San Francisco’s newest museum: The Mexican Museum, which will house the United States’ largest collection of Mexican and Latino art. The 60,000-square-foot museum will include 800 works of Mexican folk art, including pieces by Mexican muralist Diego Rivera. The museum is the realization of the dream of Mexican-American artist Peter Rodriguez. He opened San Francisco’s first museum for Latino art in a Mission District storefront in 1975. He died on July 1 at the age of 90.
