Maybe a mural, part 39: 630 North Alvernon

It's not paint on a wall, and it's not made of mosaic or tile, but it is on a wall. Is it a mural? (You can decide for yourself!)

From time to time, I post a photo puzzle like this. The last time was November 27th.

This is toward the south end of the west side of 630 North Alvernon Medical Center (located, surprisingly enough, at 630 N. Alvernon Way). I took the photo on September 26th.
