Main Street, Los Angeles, 1916
USCdigital archive/Automobile Club of Southern California negatives, 1892-1963
And now, thanks to ProphetM's dandy detective work, we know this nice image is misidentified in the Automobile Club of Southern California's archives and is, in fact, Main Street, Santa Ana(!), presumably 1916. And as these things so often play out, we also now know a little bit (more) about the San Francisco Exposition, the San Diego Exposition, the Lincoln Highway, the 'Coast Route', the Exposition Trail and the degree to which we need to remain skeptical when finding information attached to archived photographs.
