I was guessing where was this photo was shot at. It looks like the late 1940’s. My guess was either Powell by Broadway or Jackson by Powell Street. So I thought I took a walk late at night and find this location.
And there it was. 928 Jackson Street. The pillars have been removed. Next door looks exactly the same. The iron bars on the window are the same.
