Great picture. Look how the power wires all hook to the pole on a ring. Never seen that.
That is what was known as a "distro ring". Not power, ... phone.
Interesting picture, and also interesting how the bldg. in the forefront has the typical early 1900s style windows/door, yet the building to the right background almost looks like a typical 50s/60's school building.
What you see on the right are wooden, back porches on what is most likely an apartment building.
They were and still are very common on brick apartments from the late 1800s through the 1930s.
Yup, just enclosed porches for cold water flats
