Series 12, Ephemera, consists of a single copy of the July 1949 issue of the The National Geographic Magazine. The relevance to the collection is an article titled "Appalachian Valley Pilgrimage" by Catherine Bell Palmer, which includes a description of the Shenandoah Valley. The black and white photographs illustrating this article may be the work of Garber, but the photographs are not cited and there are no copies or negatives of those same images within the collection. Due to size and preservation constraints, Series 12 precedes Series 13, Photograph Prints.
