Marshall, Robert (1876?1943). Extensive Archive of Photographs, Letters, and Ephemera of Marshall the Mystic. Bulk 1890s?1900s. Massive archive documenting Marshall the Mystic, who performed variously as a hat juggler, magician, pantomimist, and medical lecturer, consisting of approximately 100 photographs, primarily cabinet card format, as well as snapshots, postcards, and glass negatives; several pen and ink drawings; and approximately 100 pieces of performance ephemera, including letterhead, business and throw-out cards, leaflets, brochures, postcards, playbills, clippings, a copper printing block, theatrical programs, correspondence to and from vaudeville performers and theater managers, and several pages of manuscript directions to stage illusions. The preponderance of the archive neatly organized in six 4to binders, with a quantity of unused letterhead and advertising material in envelopes. With three collapsible top hats of the period possibly owned by Marshall (poor). An irreplaceable archive that should be seen.
