What a fascinating thread, love all of the old photos of downtown, especially street level ones. Lots of great shots of traffic signs, my specialty.
I collect old porcelain enamel traffic signs erected from 1920 to 1960, by the Automobile Club of Southern California (ACSC), the California State Automobile Association (CSAA), and the old California Division of Highways.
I also created a web site that contains a brief history of signing in California and photos of old signs, here is the link:
