World War One-era "small box respirator" gas mask, consisting of a canvas or cloth face piece, with inset glass or resin eye lenses, and straps that wrap around the back of the head. The front of the mask has a valve located behind a cloth-covered tube that goes over the mouth and attaches to a small yellow metal box containing activated charcoal (made of peach pits or the pits from other stone fruits). The wearer would have breathed only through the mouth, inhaling air scrubbed clean by the charcoal in the box, and had their nose squeezed shut by a clip inside the mask.

Photographs of 36th National Guard Private's wool jacket from World War I, held by UNT Special Collections. This jacket was worn by George N. Rucker who was stationed at Camp Travis in San Antonio, Texas, during World War I. The first image shows an arrowhead patch with the "T" in the center represents the 36th infantry division of the Texas Army National Guard, which was made up of Texans and Oklahomans. The silver chevron patch lower on the sleeve represents stateside service of at least six months. A second silver chevron patch would have been added for an additional six months served, so we can tell that Rucker only served between six and eleven months. The red chevron near the shoulder represents honorable discharge. Image 2, front of wool jacket with two pockets on the top and bottom of each side and five buttons along the middle.
