The image is a photograph of a plaque on a brick wall. The plaque is rectangular in shape and has a gold-colored border. The text on the plaque reads "Phao Tau Hai Quan 240mm Navy Gun" in Vietnamese. Below the text, there is a description of the cannon, which is a type of naval gun used by the United States Navy during World War II. 

The plaque also mentions that the cannon was manufactured in the Saigon River, Vietnam, and that it was used by Canon 240mm de la Marine. The cannon is a French model, model 1876, type 1878, type 15, and type 15. It was manufactured by the French Navy in the early 20th century.

At the bottom of the plaque, there are two lines of text that read "Canon 240mm De La Marine" which translates to "The cannon of the Marine." The text is written in both Vietnamese and English. The background of the image is blurred, but it appears to be an outdoor setting with a green trash can visible in the background.
