The South Dakota Art Museum in Brookings, South Dakota, houses approximately 140 of Dunn's best works. Most of the works are on loan by people from DeSmet and Manchester, South Dakota, or were gifts of the artist and his family. His "often seen" painting "Dakota Woman", from his series of strong pioneer women, is housed at Dakota Discovery Museum in Mitchell, South Dakota. "The Chuckwagon" is a 1915 Dunn painting owned by the Denver Art Museum. The Smithsonian Institution notes it is a "quiet scene depicting a small group of cowboys seated on the ground beside a chuckwagon, their backs turned toward the viewer, their horses standing nearby, and a pond in the background."
