Two pipes contrast in appearance and attachment method.
A close up view of two pipes next to each other. The pipe on the left is all black with a rough and droopy surface. The pipe to the right is plastered in numerous stickers and has screws holding it onto a concrete wall. The black pipe has no stickers and is on the wall as well and has dents on the wall behind it leading from the bottom of the image to the top. A brownish orange portion of the wall is to the left of the black pipe. Light is shining on the black pipe and the wall.
