A black and white photograph of a tall building's staircase, behind glass. Photographed from the outside and from below. A play of straight and diagonal lines. Three stone steps running from bottom left to top right, with narrow parallel smal black lines between them from railings, on the background of the sunlit wall of the staircase. Then, diagonally from top left to bottom right, small lines from the window jambs in the glass in front of them, and two window jambs running straight from bottom to top.

The upper part of two buildings, photographed diagonally from below, with a patch of blue-gray sky between them. Bottom left: a triangle of the same several tall modern buildings, varying in height and depth. Rows of glass windows extending from bottom to top, light bluish-gray because of the reflective sky. The upper right side is dark and shadowed. An old building; a few shutters are visible. A black rectangular section protrudes from the center, with knobs on either side. It fits perfectly between the buildings.
