The image shows a large cannon on display in a museum. The cannon is mounted on a metal frame with two large wheels on either side. The body of the cannon is made of metal and appears to be old and weathered. It has a long, cylindrical barrel with a pointed tip at the top and a smaller barrel at the bottom. The barrel is attached to the frame with screws and bolts. There is a small plaque on the right side of the image with information about the cannon. In the background, there is a white wall and a red fire extinguisher.
