Blackstone, Harry (Henry Boughton). Harry Blackstone’s 1920s–40s Agent and Fan Correspondence Archive. Two large cartons filled with thousands of pages of original correspondence to Harry Blackstone, from young and old fans, his various managers and agents, including Lon Ramsdell, Ned Bates, Ed Milne, Doc Howe, “Kid” Long, Frederick Merrill, Forrest Creighton, and Al Grossman, as well as his property managers in Colon, Michigan, including testimonials, solicitations for employment, notices of termination of employment, and personal letters from male and female admirers. Others include Colon-based contractors and suppliers who worked on Blackstone Island. Many accompanied by mailing covers, together with handwritten programs, notices of future appearances, or suggestions for tricks and illusions (some with diagrams). Still other letters include legal correspondence regarding claims against Blackstone, route lists, theatrical managers’ messages, postcards, solicitations to purchase dogs from Blackstone, business proposals, newspaper editors’ letters, costume and other suppliers’ correspondence, Depression-era bank holiday requests for money, a hoard of correspondence from Variety editor Elias Sugarman, as well as Blackstone Stage Plot diagrams, and radio and newspaper ad transcripts. Many documents related to the show are in the archive. An irreplaceable collection, in good condition. Should be seen.
