That is a great photo gsj.
I noticed the building further down the street with the odd angular roof (it resembles a solar panel).
The building almost looks like a homage to the art deco L.A. Times Building with it's small buttress/columns.

below: Curious about the building, I looked through some other old photos of the area.

above: From this different view I can now read what's written above the angled area in gsj's photo.
It says Times Mirror Printing and Binding House.
But why does the angled part of the building now appear in the middle of the roof instead of at the front like in the gsj's photo?
The simple answer would be that the angled area is on a different building BEHIND the white building with the arched windows.
But even this seems wrong when you consider the cross street in the distance
For the life of me I can't figure it out.
