Chalk shapes and lines adorn a concrete sidewalk's surface.
An outdoor, close up, overhead view of 3 similar sized chalk shapes drawn inside a white chalk square on a concrete sidewalk. The top shape is a square colored to be gray-blue. The square is near the top edge of the white square. A dull lime green chalk circle is drawn near the bottom left edge of the white square. A bright blue, equilateral triangle is drawn near the bottom right edge of the white square. A faint vertical red chalk line is to the right of the white square. The sidewalk has faint brown stains on its surface.
