The collection consists of photographs, newspaper clippings, cartoons, and contemporary ephemera related to World War I, mounted on scrapbook leaves; many are captioned. The leaves have been disbound, housed in mylar sleeves, and boxed by volume. The handwritten captions were likely added by Munn. Many of the photographs appear to have been prepared for publication, and display crop marks and painted alterations of images. The photographs are roughly arranged by country, with the greatest representation of American images, followed by English, French, Italian, and German, with a sampling of other nations represented, such as Greece and "Mesopatamia" (i.e., Iraq). There is a wide range of subjects of the photographs (which are of varying dimension), including naval construction, manufacturing, aviation, destruction, weaponry, treatment of wounds, and images from trenches.

The images originate from a wide variety of sources. Many come from the U.S. Signal Corps ("Signal Corps USA"), which provides and manages communications and information systems support for the command and control of combined arms forces. In additon, there are printed ephemera. Around 30 private photographers or illustrators are given credit, including Alfieri, a London photographer; C. McKnight-Smith, an American painter; Underwood & Underwood; and Harris & Ewing. Most items, however, do not list their source. Where no labeling was available, staff provided information in square brackets.
