The collection consists of papers of the Klassen family. A substantial portion of the collection is letters written by Albert Klassen and his wife, Delma Jean Klassen. The letters were written from October 1943 to July 1944, when Albert Klassen was serving in the Pacific Theater aboard the USS Carina. These letters employed a code that the Klassens developed in order to bypass redactions from Navy censors. The collection also includes a scrapbook containing photographs, correspondence, newspaper clippings, and ephemera; and photographs, correspondence, and records relating to the Grace Peck House in Portland, Oregon, which Suzanne Klassen owned from 1978-1985, and the house's designation as a historic landmark.
