The Joseph F. Wehner Collection is primarily comprised of visual and textual materials related to the life and World War I military service of Joseph Wehner.

The collection includes correspondence to his sister Hazel, as well as correspondence about Wehner's death written to various members of his family. The photographs in the collection depict Wehner during his aviation training and during his time on the front in France. Of note are several decorative certificates that he received for his service.

In addition to the materials directly about Wehner, this collection also contains ephemera concerning Wehner and his friend and wingman Frank Luke, some dating from the decades after the war. These items include newspaper and magazine clippings about Wehner and Luke, as well as materials written by the Champlin Fighter Museum in Mesa, Arizona (now closed). Taken together, the items in this collection give a limited but personal insight into the life of Joseph Wehner from approximately 1913 to 1918 and also documents the ways in which he was memorialized in the years after World War I.
