In this photo, we see a couple of things we no longer see around LA: a Los Angeles Railway bus and a Van de Kamp’s Bakery with its iconic windmill. This one stood at 8328 Wilshire Blvd at the corner of Tower Drive (where a Coffee Bean & Tea Leaf café now stands.) This photo was taken by Ansel Adams, who was commissioned in 1939 by Fortune magazine to take photos around Los Angeles.
From the 1939 Los Angeles City Directory:
That same view in January 2018:
The two shots of the Van de Kamps bakeries appear to be of different bakeries on different corners. The adjacent buildings are not the same.
The way the building extends down the street to the right seemed very similar. Plus I fact-checked this photo on two other site and they both said this was the corner. Of course, they could both have been wrong, too!
