WWI US Air Service (USAS) Officer Collar Insignia with Hollow Back

This is a World War I United States Air Service officer collar insignia with beautiful detailing on the wings, both front and back.

Circa World War I.

Approximately 1-3/4" in height and 1" in width.

None.

This is from a United States Army Air Forces collection which we will be listing more of over the next few months. MBEX11 LADEX5/11 SADEX5/15

7+ (Very Fine+): The insignia shows some small areas of light wear and has a handsome tarnish.

As with all my artifacts, this piece is guaranteed to be original, as described.
