Gray stone wall bears mysterious markings with "STONE" in reverse.
A close-up view of a gray stone wall on a building that has black smears on it randomly and the word "STONE" in black backwards on it in the middle. It has black lines painted above and under it on the concrete. There is part of a concrete column on the right under it, resting under the wall. There is a jagged concrete edge above "STONE" going across horizontally. Part of a white light fixture hanging down on the right is visible. On the left, near the column under the wall, there is a sensor and a security camera attached to the ceiling. There is part of a window visible under them on a wall.
