Depression-era California comes alive in a clip from the Prelinger Archive's HD video collection of 35mm stock footage. Shots like this were usually projected behind characters in a car on a sound stage, to create the impression of driving. Rick Prelinger, the creator of the archive, describes the process and shares another clip of 1940s downtown Los Angeles here.
