The image is a display case in a museum. The display case is made of glass and has a black and white photograph of a train track in the background. On the left side of the display case, there is a large cannon with a long barrel and a handle. Next to the cannon, there are several smaller photographs and information about the cannon. 

On the top right corner of the image, there appears to be a banner with text that reads "By the spring of 1864, the war has transformed Atlanta and many smaller Georgia cities and towns into centers. By tobacco-spitting grown from a few to become a red city, the storehouse." On the bottom left corner, there seems to be another display case with more information about a cannon and other artifacts.

The overall theme of the exhibit is that the cannon was used during the American Civil War and that it was a symbol of the country's rich history and culture.
