The image shows a small, round, bronze carriage bumper. It appears to be made of metal and has a smooth, polished surface. The bumper has a small hole in the center, which is likely for the carriage to be attached to. The body of the bumper is decorated with intricate carvings and patterns, and there is a label on the right side of the image that reads "Bronze Carriage Bumper" in Chinese characters. The background is a plain white surface.
