Found on EBay -- Broadway and 6th
This postcard view looking north on Broadway from 6th Street, showing the Los Angeles Examiner Building and the Pantages Theater, has been listed on EBay. The vendor guesses that the photograph was taken in the 1930s, but I suspect it’s much earlier. Construction for the last Examiner Building began in 1913. The Pantages Theatre moved to another building in 1919.
Notice the traffic semaphore and the UM 1906-style streetlights.
Bidding starts at $4.50.
