Series III: Memorabilia contains items not related to specific compositions by Schickele. It includes personal correspondence, photographs and printed images (such as book covers, images printed on loose calendar pages, and blank postcards), concert programs, pamphlets, newsletters and brochures, newspaper clippings and copies, tape cassettes (containing music sent to Schickele by other composers and recordings of works by W.A. Mozart and possibly C.P.E. Bach), and scores sent to Schickele by other composers. The series includes two sets of stereograph images dated 1874 and 1903.
