The collection contains a very small amount of original material, including correspondence from Wallace Mitchell and to the Board of Trustees in 1946; two scrapbooks containing clippings about Sepeshy's life and work between 1926 and 1966; and an original manuscript which Sepeshy co-authored with Robert Rothman in 1953. The bulk of the collection is comprised of copies of materials including commencement speeches given by Sepeshy between 1958 and 1965 and an oral history interview with Dennis Barrie given in April 1973 (from the Archives of American Art), and copies of four scrapbooks of clippings that cover 1925-1953.
