Thanks for the address

If you look at the 1932 photograph again you will see that there is also a large window behind Ms. Blondell and
, judging by the natural light on the right side of the photograph
,
there is also a large window directly across from her.
So I'd say Ms. Blondell is sitting in the smallish 'room' that projects out from the house which would give us the three windows.
What do'ya think?
It's also facing south and I'm pretty sure I see the Baldwin Hills in the 1932 photograph. (unless that dark area on the horizon is smog)
EDIT:
I've already changed my mind.
What I circled above is an awning leading leading out to a deck.
Now I believe Joan's 'studio' with the large window(s) is to the right of the awning. . .ummm
