This painting depicts a historical document related to the California Land Grant Study. It features a map of California with pastel colorations indicating different areas, along with script text detailing the study by the Index of American Design and related historical information. The decorative vertical panels on the sides mirror each other, depicting cultural artifacts such as hats, cacti, and tools. The top part shows flags of Spain and Mexico, along with architectural elements. Below, there are detailed narrative scenes with figures dressed in historical attire, interacting in a landscape setting, possibly representing the period of Spanish and Mexican rule in California. The style reflects WPA murals from the mid-20th century.
