Southern California Modernist artist Helen Lundeberg (1908-1999) designed the History of Transportation Mural in Inglewood in 1939 as a project of the Works Progress Administration. The mural is 8 feet high, 240 feet long, and is comprised of 60 mosaic panels mounted on a curved cast concrete wall.
The mural depicts the historic inhabitants of the Centinela Valley including Native Americans, Spanish Missionaries, and Anglo settlers. The mural shows forms of transportation including walking, ox-drawn carriages, steam trains, automobiles, and airplanes.
The History of Transportation Mural is made with petrachrome mosaic, a process designed by the WPA specifically for California's hot, sunny climate. Petrachrome mosaics were made with colored, crushed stones embedded in tinted concrete mortar. The WPA designed the petrachrome process to be labor intensive so that the projects would employ a large number of laborers and artisans. The Inglewood mural is one of the last remaining petrachrome artworks in the country.
Here is a detail depicting a boy on horseback waiving at two girls in an ox-drawn cart:

By the 1990s, the mural was severely damaged from weather, pollution, car collisions, and vandalism. The City of Inglewood and a variety of preservation groups raised $1 million in grants from the Getty, the California Heritage Fund, the California Cultural Historical Endowment, and other private donors for a major restoration and re-installation that began in 2001 and was completed in 2007.
The Inglewood transportation mural is appropriately located just a few miles East of LAX International Airport.
Here are some closer details from the mosaic. Some of the color areas are delineated with thin, inlaid brass outlines.

The History of Transportation Mural is located at the corner of Manchester Boulevard and Grevallia Avenue across the street from Inglewood High School just a few blocks away from Randy's Donuts. There is more information about the mural, the restoration effort, the petrachrome process and artist Helen Lundeberg available on the City of Inglewood's website.
