Very nice photo.
The taller, elegant building still exists. It's the home of an exclusive social club, called the Jonathan Club, the address of that building is 545 S. Figueroa Street. That structure was built in 1924. Interesting to me because there's another social club nearby with its own taller building called the California Club, adjacent to the main library; I wonder if they competed with each other for members; or not. I'm sure they were both very exclusive, and probably still are-- though I know that the California Club isn't as "exclusive" as it was; I've been inside the California Club; I know that a long time ago, it didn't even allow Jews.
Whatever secrets and stories the Hotel Clinton could have told, it's been silenced forever-- that's where the Arco Towers-- uh, City National Plaza, is now.
Here's a long-shot of that intersection, courtesy LAPL, in 1952
