Check out this video, an MGM presentation of James Fitzpatrick's "Voice of the Globe" Travel Talks, featuring footage from Los Angeles and Glendale, California in 1946. The video starts with scenes of California wildflowers, but the really interesting scenes start 3 minutes into the video. There are clips of Hollywood Boulevard, the Chinese Theater, CBS Studios in Hollywood, NBC Studios in Hollywood (now demolished), the Fairfax Farmer's Market, and even Forrest Lawn Cemetery which I just previously did a post on.
I think it's very interesting to see what's changed since 1946 and what looks pretty much the same. My two favorite clips are those showing the old deco NBC building before it was demolished and the Chinese Theater before the huge Hollywood & Highland complex stood next door.
