The Kress G. Drew World War I Collection consists primarily of visual materials documenting the World War I military service of Kress Gregg Drew.

The bulk of the collection is made up of visual materials, comprised of 74 loose photographs, 2 digital images, 2 postcards, and 54 prints affixed to documents. Of particular note are the 57 photographs and accompanying notes related to sighting planes. Two 11x15-inch presentation boards with 1.25x2-inch photos affixed to them were possibly used for training. One titled, "Positions of Planes in Ring Sight at Various Angles of Approach From 'Dead On' to 90°" has 19 prints showing positions of planes in ring sights. The second board is titled "Method of Marking Films to Show Errors in Deflection and Elevation" and includes eight images of planes in various positions in ring sights. One loose 4.25x6-inch print repdroduces this board and two other 9x13 cm prints also have images of planes in ring sights. Additionally, a notebook with both handwritten and typed notes and 27 1.25x2-inch prints affixed, includes additional information on sighting planes.

In addition to the gunnery sighting photographs are 71 snapshots and two digital images, some possibly taken by Drew but many likely collected from other sources. A portrait of Drew depicts him in flight gear shortly after he had begun his training. This print is a modern reprint, but a digital scan taken from the original vintage print is also present, as is a scan of a group portrait of the squadron football team. Twelve photographs depict various aircraft and four images show guns and tools. Thirty-three images show candid scenes of soldiers and military encampments, including soldiers at leisure and marching, and scenes of wartime desctruction. One of these images includes a few Black soldiers. Note that two images include graphic depictions of bones and skulls. Three prints are "living insignia" portraits of the Second Aviation Instruction Center. An additional 18 photographs and two postcards show scenes from France, including towns and street scenes, cathedrals, and châteaux. A portrait of a French nurse is also included. ASide from the portrait of Drew, none of the photos has captions or identifications of the people depicts.

Relatively few textual materials are present in the collection, but they consist of a few memos, military orders, and documents relating to aerial gunning and the Hythe Mark III gun camera from 1918. An employment application from 1936 provides additional biographical information on Drew.
