We have visited numerous military academies (Page, Black-Foxe, Pacific, etc) over the years on NLA.
But I don't believe we have seen the Urban Military Academy.
Here's a rare aerial. (I don't know if any of these buildings have survive)
ebay
I'm not sure why someone penned a circle around that one tiny person (as if they could tell who it was!
lol)
If you look closely, U R B A N is spelled out on the lawn. (detail below)
Also included were these three family snapshots.
eBay
side note:
The more I look at the three snapshots, the more I think they show a different military academy.
(the buildings don't resemble the buildings in the aerial...and it looks like autumn in a less moderate climate than L.A.) -but I could be wrong of course.
-perhaps the seller just added the three snapshots to entice a buyer. (& they're unrelated to the aerial)
At least we know the aerial is of Los Angeles.

Here's some brief information on the Urban Military Academy:
"
Urban Military Academy was a boarding and day school in Hollywood, California, for boys between the ages of six and fifteen, founded in 1905 by Mary McDonnell
(on Melrose Avenue at Wilcox; it later moved to 11600 Beverly Blvd.) and at the time it opened "the only private school for boys in the City." Its commandant was
Major Harry Lee Black, who in 1928 helped found Black-Foxe Military Institute on Urban's original site."
