Hello there from Ojai, I have been a lurker for several months and decided I must be a closer follower of this fabulous site. I born, lived and worked in L.A. till I moved to Ojai after retirement. It has changed very much since my youth in the 40's,50's and 60's and I miss the old L.A. very much. This site is my time machine.
The "Bell" shaped items on the Wilshire Blvd. unique streetlights are probably bust stop signs. If you look closely you can see a bus stopping at the corner. Bus stops were usually on the corner then by the way. The photo with the Chevrolet dealer is Sunset Bl. I believe.
