The image shows a large artillery cannon on display in a museum. The cannon is mounted on a long 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. In the background, there is a black steam locomotive and a group of people looking at the cannon. The museum has a high ceiling with large windows, allowing natural light to enter the space. A plaque with text is placed on the ground next to the cannon, likely providing information about its history.
