I just happened upon this excellent rppc photograph of a boarding house located at 126 W. 21st. Street, Los Angeles in March, 1915.
... HERE
There are some very interesting looking boarders in this pic. I especially like the gentleman in the chair on the right.
The three ne'er-do-wells
on the top step look like they'd be fun to hang-out with at the local pool hall.
...(actually, they're sitting in CHAIRS too)
Is that a vent, or a trap door, to the left of the porch?
...(perhaps a distant relative of the owner is chained up in the basement)
Note the Room & Board sign on the pillar.
The reverse.

I wonder if the man in the chair is the person associated with the USC medical school student. (I wonder if he's a student or a professor)
