The item featured here is a US Army gas mask. As issued during World War One. The mask and tank are in rough shape, but the bag is in great shape with hand drawn art, probably by the soldier who carried it, Corp. William C. Huxhold. This is a very neat bag, as an art major I enjoy seeing the artwork the soldiers did during this conflict.

WWI US ARMY GAS MASK - Chemical warfare was widely used during WWI. All sides involved in the battles used mustard gas at one time or another. The need for soldiers to have protection against the gas became apparent very quickly.
The gas mask shown in this page is one of the early examples of the items worn during the war. The mask came in a cotton pouch that had a long strap. The carrying case was worn in front of the chest during the battle. This was accomplished by shortening the strap and tying a rope around the torso. This would secure the mask during brisk movement. The mask was carried like a purse during non-combat time.

WILLIAM CHARLES HUXHOLD was born on January 20, 1897 in Havana, Illinois, as the son of Karl August Huxhold (1860-1925). During World War One, Corporal William C. Huxhold enlisted in the Army and was with Company K, 329th Infantry Regiment, 83rd Division with the American Expeditionary Force in France.
There's a WWI Draft card for Wm. J. C. Huxhold, living in Chicago, Illinois during his draft in 1918, son of C. A. Huxhold. I'm not finding any military record other than the WWI draft card.

He married Gertrude Veronica Mumm, they had one son, William John Huxhold (1929-2003).
