Color slides developed by Duncan and originally arranged in ten film boxes that document sights from his service in the Korean War and other events in his life from circa 1950 to circa 1958. Slides are in the original order and separated into groups based on their original box. Items in the 100’s correspond with box 1, the 200’s correspond with box 2, and so on. Titles were given to photos based on Duncan’s own descriptions on the back of the slides. Additional titles were given by Duncan’s children; some photographs are still untitled due to poor quality or ambiguity.
