"Beginning in 1938, Ms. Wagner and her then-husband Bill Lippincott took over the Wide Ruins Trading Post on the Navajo Reservation where they lived and worked throughout the World War II years. Ms. Wagner proved to be a skillful amateur filmmaker who documented life on the trading post with her 16mm camera, which she kept ready to go in her saddlebag." Southwestern Archivist, Nov. 2005, 33.
