The image is a side-by-side comparison of two photographs of an old wooden door. On the left side, there is a close-up of a metal door knocker on a wooden surface. The knocker is made of metal and has an ornate design with a curved handle and a round finial at the top. The handle is decorated with a floral pattern and has a small knob in the center. The door itself is made up of two panels, one on the right side and one in the background. The wood appears to be aged and weathered, with visible cracks and chips in the surface.
