As promised, here are some more images from Julius Shulman's 1965 photoset
"Job 3876: William L. Pereira and Associates, Occidental Center". The set includes some great shots of the exterior, but they don't add much new to the thread. I wonder how many of these features remain. I'll start with this large theater.
I'm guessing that this is a dining area, although I can't see a food counter.
Here's a very fancy-looking boardroom.
And a more modest meeting room.
There are a couple of pictures of this garden taken from level with the base which made me think it might be the Japanese garden, but then I found this elevated view.
A lower angle shows the three pools flowing into each other.
The garden continued along this tiled area.
These are the walkways above.
The elevator lobby looks quite plain when compared to examples like the Richfield Building. Of course, the Richfield was torn down three years after these photos were taken.
I'll finish with this one which appears to show the bar area leading to the restaurant which started the recent discussion of this building.
