David at Retail Memories From Coast to Coast uploaded 2 videos (split) about Hillsdale Shopping Center in San Mateo, California, as it was in 1957 when it opened.
The videos show the center before it was enclosed, activities related to it, and vintage fashions, stores and signage. They serve as almost a class as to "how to shop" in what was then a new style of commerce.
Check them out. I think you'll enjoy them.
A Shopping Center is Born
