Looks to me like it was Fleet Week in LA some time during WWII. I count five or six sailors in this candid color shot of the NBC radio studios on the corner of Sunset and Vine, including the officer on the steps leading into the building. Even the kid in the striped shirt is getting into the swim with his white sailor hat!
