The image is a photograph of a sign hanging from the ceiling of a building. The sign is rectangular in shape and has a white background with black text. The text reads "SUNG THAN CONG - TK. XVIII-XIX" in Vietnamese. Below the text, there is a list of cannons from 18th to 19th centuries, with the dates "Canons 18-19th century" and "Siecle" written below. The number "10" is written in blue on the top left corner of the sign. The background is blurred, but it appears to be a wooded area with trees and greenery.
