The image is a photograph of a blue sign with white text on it. The sign is located in a park or outdoor area with trees and bushes in the background. The text on the sign is written in Vietnamese and appears to be a list of information about the U.S. Army in Vietnam. 

The list includes information about different types of helicopters, such as UH-1 Huey, which is a type of helicopter used by the United States Army during World War II. The list includes details such as the type of aircraft used, the size of the aircraft, and the location of the helicopters.

At the bottom of the sign, there is a note that reads "By April 1969, some UH series helicopters were serving the U." The sign also mentions that the helicopters were served in Vietnam by April 1969.
