The U.S. Air Force can trace its roots back to the Aeronautical Division, Signal Corps, formed as a part of the army in 1907. In 1947, after several changes, W. Stuart Symington was sworn in as the Air Force's first Secretary, and it became its own branch. Among other things, they assist in the recovery of troops and air support of other armed forces. This Holographic Decal can be used by current and past members of the Air Force to show pride in their branch and those with loved ones in the Air Force to show their support.
