The image is a photograph of a historical marker in Vietnam. The marker is rectangular in shape and has a gold-colored border. The text on the marker reads "Sung than cong" which translates to "Cannon" in English. Below the text, there is a description of the cannon, which was made under the Chinese dynasty, century 18, and discovered in the South of Vietnam. 

The marker is located in front of a brick wall, and there are several large wooden barrels on either side of it. The barrels appear to be old and weathered, with some of them having cracks and chips in them. The background is blurred, but it appears to be an outdoor setting with a brick pavement.
