This is from 1916 and shows Glick Alley which is in Shaw. It was on Square 442, which is between 6th and 7th, R & S Streets and Rhode Island Avenue NW.
Glick Alley, as far as I can tell, no longer exists.
No inside plumbing for these Glick Alley homes. As I remember it, the lack of plumbing made something a slum dwelling.
