I think the weight of evidence suggests that the Mackey (Pearl) Apartments photos date from after 1939. Thanks for all the follow-ups.
Also, thanks to
e_r for identifying my mystery airplane at Westchester Enriched Sciences Magnets. They didn't do aviation & aerospace classes when I was at school!
Finally, thanks to
Flyingwedge for your personal memories and photo of yesterday's Julius Shulman subject.
-----------------
The Sunset Medical Building at 6642 Sunset Boulevard has been mentioned a couple of times before on NLA, but I can't find any pictures of it. This is
"Job 0136-MB: Sunset Medical Building (Los Angeles, Calif.), undated". The photoset is undated, but the cars in one of the later images suggest this may be closer to 1939!
I know that these two shots of the entrance are fairly similar, but I decided to include both of them.
Now, a wider view. I've omitted a similar, tighter image from across the street. On the left is Westmore's Salon of Beauty, as seen in
post #6078 by
GaylordWilshire.
The set also includes these two interior pictures.

From the building records, it looks like 6642 was built as a residence in 1921. The description of the Shulman photos names Rudolph M Schindler as architect, and it's his name that appears on the 1936 alteration permit. There also seems to be a demo permit dated as
early as 1967. Here's the view today - it's just a parking lot. Check out
