The learning tree, Los Angeles, 1975. Plaza de la Raza, exterior facing parking lot, 3540 North Mission road (at Lincoln Park Avenue). Originally David Alfaro Siqueiros was commissioned by the officers of Plaza de la Raza to paint a mural, but he died before doing it. Flores was selected as his replacement. The mural is a tribute to the contributions made by Chicano working people -- campesinos, garment workers, welders, and retail clerks. Also present are portraits of some of the local leaders who have contributed to the community. Liquitex acrylic on wood, 504 square feet, by Alfredo Diaz Flores. -- Dunitz, Street gallery, p. 291, #22.
