The image shows a long wooden shelf with a collection of antique door knockers hanging on it. The knockers are made of metal and have intricate designs and patterns on them. They are arranged in a row and are of different sizes and shapes. On the left side of the shelf, there is a large black door knocker with a circular handle and a circular finial in the center. Next to it, there are several smaller black door handles with intricate designs on them, including a lion's head, a crown, and a bird's head. 

On the right side, on the bottom right corner of the image, there appears to be a small glass display case with a metal stand. The shelf is mounted on a white wall with a framed picture hanging above it. In the background, there seems to be an old-fashioned room with a wooden door and a window.
