The Ralphs is probably the store at Sherman Way and Woodman. There's a 4/16/1961 article in the LA Times announcing its groundbreaking. An article from a year later expected it to open in June, 1962. According to that article, "Basic construction materials in the one-story building include brick, and tapered steel girders. Decorative steel columns will highlight the facade and an extensive use of glass and exotic mosaic paneling will accent the design." I find it fascinating what qualified as news back then... It's still a Ralphs though much more boring that it probably was when it opened.

The Vons is on Van Nuys Blvd just south of Vanowen and is a Jons today. I recently help run a volunteer office in the same shopping center and researched the store's past so I know it was a Vons. And the palm trees are still there. In this shot you can see a truck in the loading dock ramp, which goes under part of the parking lot.
