The Superba, Clune's and Pantages
We're looking south across the east side of the 500 block of Broadway in this early postcard view that's in Nathan Marsak's collection. It's a view sometime between 1914 and 1920. With the oval roof sign, the theatre closest to us is the Superba (1914), followed by Clune's Broadway (1910) and the Pantages (also 1910).
The card appears on the Skyscraper.com discussion thread Noirish L.A. where Mr. Marsak has a whole set of downtown postcard views, as well as on Flickr.
See our pages on the Superba, the Cameo and the Pantages (now the Arcade Theatre) for many more views of the block. The Superba got replaced by the Roxie but the Cameo and Arcade are still there.
