Have you run into any of these cards? The Frasher Foto Cards were almost all black and white and usually with a description on the front.
They're the work of Pomona photographer Burton Frasher (1888-1954). His cards were sometimes fairly standard but he also had an eye for quirky subjects and interesting compositions.
The Pomona Public Library's Frasher Foto Card Collection is a great place to browse. There are over 7500 views in the collection representing sights all over southern California.
Here we have a 1946 view looking west on Hollywood Blvd. past the Hawaii Theatre. Look at the interesting changeable letter roof sign. It's not advertising a Chase Bank branch in the lobby. The film is "The Chase" with Robert Cummings. At other times the sign simply said "Hawaii."
See the Hawaii Theatre page for a few more views including a recent interior view by LAHTF's Don Solosan.
