The image is a photograph of a sign in a grassy area. The sign is rectangular in shape and has a blue background with white text. The text on the sign reads "KT-1" in Korean, which translates to "Korean Air Force" in English. Below the text, there is an image of a fighter jet, which is a type of aircraft used by the Korean Air Force during World War II. 

On the right side of the sign, there are three smaller images of the fighter jet. The first image shows the jet in flight, the second image shows it in mid-flight, and the third image shows an airplane in flight. The fourth image shows two smaller images, one of a red and white fighter jet and the other of a blue and white airplane.

The sign is mounted on a metal pole and is located in front of a grass field. In the background, there appears to be an airplane parked on the ground.
