The 90th Infantry Division was formed August 25, 1917 and began training at Camp Travis, Texas, in preparation for action in the First World War. The Division began sending units to Europe on June 5, 1918. The 90th ID, also known as the Tough 'Ombres, fought in many battles to include St. Mihiel and the Meuse Argonne. They were also an integral part of the occupation forces, occupying Bernkastel-Kues along the Moselle River, and stayed in Germany from the end of the war until May 1919.

To celebrate the culmination of the Division's occupation of the area surrounding the town of Bernkasel-Kues, the 90th Division held a "Circus and County Fair" May 1-2, 1919. The fair included a parade, clowns and acrobats and a "Wild West Show." For the event, the Division created Teeohs, money name after the Division's patch. The script was used by the Soldiers for food and activities at the fair.
I found this great German website that discusses the Circus and County Fair that the Division held here. (I translated the website using Google Translate).
