The image shows a close-up of a door knocker in the shape of a horse's head. The knocker is made of brass and is attached to a wooden door. The horse head is in the center of the knocker, with its head facing towards the right side of the image. The head is intricately detailed, with the mane and tail flowing in the wind. The door appears to be old and weathered, with visible cracks and chips in the wood.
