The image is a photograph of a plaque on a brick wall. The plaque is rectangular in shape and is made of metal. It is mounted on the wall and has a textured surface. The text on the plaque reads "Pearl Street Mall Sundial, erected by the City of Boulder Landmarks Preservation Advisory Board to recognize and commemorate historic preservation in Boulder. Funded in honor of William D. Carter by the United Bank of Boulder, its board of directors and staff." The plaque appears to be old and weathered, with some cracks and chips visible on the surface.
