Really cool night shots, ethereal! I like.
Here's a more ordinary shot of Washington and Figueroa Streets in 1942. The caption says that a streetcar is blocking traffic. Notice the old California state highway route marker shield; I read somewhere that they were originally intended to be shaped like a California miner's spade. They of course have since evolved into the green California state highway route markers you see today with somewhat of a similar shape.
