This photo that LAboomer52 posted reminded me of the open question from when it was posted way back in the thread. What was that odd walled building center left?
I am now wondering if it had been a hanger for the airfield that was once on the corner of Wilshire and Fairfax??? It looks a lot like a large cavernous maintenance hanger that used to be here at the San Diego airport.
In this 1929 photo of Wilshire looking east from Fairfax, you can see the transition from the characteristic Los Angeles Wilshire street lights, to the Beverly Hills Wilshire street lights seen in the mystery photo.
