The image shows an old-fashioned cannon on display in a museum. The cannon is made of metal and has a large wheel on the right side and a smaller wheel at the bottom. The wheel is attached to a metal frame with a chain. The body of the cannon is covered in a black metal cover, which appears to be made of wood or metal. The cover is tilted slightly to the left, and there is a small window on the wall behind it. The floor is covered with a beige carpet.
