Here's the Ralphs on 3rd Street and Wilshire Blvd. in Santa Monica; it was designed by Stiles O. Clements, and built in 1939-1940.

Here it is now, courtesy of Google Earth. It's now a Barnes & Noble bookstore, and 3rd Street is now the Third Street Promenade. It's all gutted, and they added an upper story.
