The "Leaping Tiger" insignia represented the 141st Aero Squadron of the United States Army Air Service (USAAS) during World War I. This emblem was likely cut from the fabric of a squadron aircraft from the period.
The 141st Aero Squadron was a pursuit squadron in the American Expeditionary Force. The squadron flew its first combat patrol in late-October 1918 and saw limited combat. Following the cessation of hostilities, it was reassigned to participate in the post-war occupation of the Rhineland in Germany. It relocated back to the United States in 1919.
