I lived in Playa del Rey for years just a few blocks from the house on the hill in the 4th pic.

A few of the local coffee shops and restaurants have some of these old photos and I always found it amazing that you could still see the resemblance despite all the development.

The building being built along the road in the 4th pic is a karate school now. The lagoon is a few ugly condos, a baseball field and mostly mud now.
