The image is a black and white photograph of a group of men working on a large cannon in a wooded area. The cannon appears to be old and weathered, with a large wheel and a long barrel. The men are gathered around the cannon, some of them are standing and some are kneeling on the ground, while others are working on it. There are trees and bushes in the background, and the ground is covered in fallen leaves and debris. The image appears to have been taken during the early 20th century.
