This photo has been floating in
and out of Facebook of late, each time from a different source.
Most recently it appeared on a site called "Hollywood's Garden of Allah
Novels," which has me scratching my head. Ironically, it's the
site with the actual photo provenance, which says it illustrated an
article in the February 3, 1941 Los Angeles Herald-Examiner. I guess
you've figured out those are former streetcars, each of which apparently
contained three units renting for $30 a month. The Hollywood site
didn't have an address and guessed that this location was in San
Diego. The Vintage San Diego site said it was on the northeast
corner of India and Laurel, which -- if you know Laurel Street Hill --
doesn't feel right. The snippet below, from the 1943 City
Directory, seems to back up that assertion. So, Laurel Street Hill
would be a couple of blocks to the right, and Lindbergh Field would be
over your shoulder to your left.
