the contributions of Chicano artists as part of the sweeping arts initiative known as "Pacific Standard Time: The Art of Los Angeles 1975-1980". Each artist of this historically significant group is responsible for bringing well-deserved recognition to Chicano Art and, in no small way, have been instrumental in paving the way for the Chicano/Latino artists that have followed. Exhibitions and public art After having had well-received exhibitions in the Los Angeles area, the group's breakthrough came when LACMA made the decision to mount a major Los Four exhibition titled Los Four: Almaraz, de la Rocha, Lujan, Romero (Feb. 26–Apr. 7, 1974). In doing so, LACMA became the first mainstream museum to recognize the importance of Chicano Art as a unique school of American art. Along with their exhibitions, the members of Los Four are responsible for many of the most well-known murals of the period. Frank Romero painted several murals around Los Angeles, including Going to the Olympics on a wall of the Hollywood Freeway in downtown Los Angeles. The mural, originally created for the 1984 Olympics, was vandalized over time and "whitewashed" by CALTRANS as part of their graffiti abatement program. In 2013, the Mural Conservancy of Los Angeles restored the popular mural along with 5 others on the freeway. Judithe Hernández painted twelve murals in the Los Angeles area between 1969 and 1982, two of which were painted in collaboration with Carlos Almaraz at the Ramona Garden Housing Projects. In 1976, she was one of the artists who painted the first 1000 feet of the Great Wall of Los Angeles. In 1981, she was commissioned by the Los Angeles Bicentennial Committee to create the city's official bicentennial mural commemorating the founding of the City of Los Angeles in 1781. The 3-story mural "Recuerdos de Ayer, Sueños de Mañana" was painted on the north facade of the Brunswig Building next to the Placita Church on Spring Street. Carlos Almaraz also painted numerous significant murals in the Los Angeles area. With John Valadez, he painted the 200-foot-long Return of the Maya in Cypress Park, La Adelita in the Ramona Gardens Housing Project with Judithe Hernández, and California Dreamscape (completed after his death). He and Judithe Hernández also painted murals for Cesar Chavez and the United Farmer Workers Union. Three members of Los Four have received major public art commissions from the Los Angeles County Metropolitan Transportation Authority (LAMTA). In 1992,
