Via both LAist and Metro's The Source blog, here's an amazing silent film taken of Los Angeles circa 1917. Apparently Ford did a number of these films as educational travelogues. As LAist notes:
Check out the hustle and bustle of L.A.'s "575,000 souls" in the retail district, shopping for curious wares from the Orient, chugging up Bunker Hill on Angels Flight, and riding their horseless carriages through Downtown's tunnels.
I love this film simply for the ability to see the old buildings of Downtown Los Angeles (such as Clune's Auditorium) as living, breathing buildings and not just old black and white photos.
