In 1942, U.S. Office of War Information photographer Alfred T. Palmer took color images at the Douglas Aircraft Plant in Long Beach and the North American Aviation Plant in Inglewood. Today, these images are available through the Library of Congress Prints and Photographs Online Catalog. These 20 images are from a subset of color images from the U.S. government's Farm Security Administration and later the Office of War Information.
From the Library of Congress website:
Photographers working for the U.S. government's Farm Security Administration (FSA) and later the Office of War Information (OWI) between 1939 and 1944 made approximately 1,600 color photographs that depict life in the United States, including Puerto Rico and the Virgin Islands. The pictures focus on rural areas and farm labor, as well as aspects of World War II mobilization, including factories, railroads, aviation training, and women working.
The original images are color transparencies ranging in size from 35 mm. to 4x5 inches. They complement the better-known black-and-white FSA/OWI photographs, made during the same period.
Palmer worked for the Office of War Information from 1942-43. Palmer was born in 1906 and passed away in 1993. For more on Palmer, check out his official website: Alfred T. Palmer: 20th Century American Photographer.
