The mural, painted by the famed Mexican artist Diego Rivera, is a portal into another time and place. Measuring over 5 feet tall and nearly 9 feet wide, the fresco, completed in 1931, depicts workers tending an orchard in California, bathed in the glow of white-blossoming almond trees. A basket holding the fruits of their labor, surrounded by children with outstretched arms, appears in the foreground.
