Here's a home movie of portions of Los Angeles, shot in 1956. 

Begins with the title "It is lucky to live in America." Shot of a Los Angeles County map with the population "518 million" listed on it. The next map shot says “Los Angeles: We live here.” 

Close-up of a pink rose. 

A woman walks through the parking lot next to the "Carnation Milk" building, which was on 5055 Wilshire Boulevard. 

The door of an office building lists the names of medical doctors. 

Wide shot of Griffith Observatory, which is near the Hollywood sign.

The clip ends with a series of wide shots of Los Angeles, including what appears to be downtown LA. City Hall appears to be visible in the distance.
