The image shows a long, cylindrical object, possibly a cannon, displayed in a museum. The object appears to be made of metal and has a shiny, metallic finish. It is mounted on a wooden base and is positioned in front of a large window with a view of a building and trees outside. On the right side of the image, there is another object that looks like a submarine or a submarine. The background is blurred, but it seems to be an indoor space with a high ceiling and large windows.
