The image shows an old cannon on display in a museum. The cannon is mounted on two wooden blocks, one on top of the other. The body of the cannon is made of metal and appears to be weathered and aged, with visible signs of wear and tear. It has a long barrel with a handle on one end and a trigger on the other end. In the background, there is a large wheel with spokes, which is likely part of a larger cannon. The floor of the museum is tiled with a geometric pattern.
