Blackstone, Harry (Henry Boughton). Archive of International Magic Circle Documents and Ephemera. Bulk 1930s. Approximately 50 pieces, including letters to Blackstone or between other club members, councilmen, and heads of the organization, on matters ranging from the club's often shaky finances, original sketches of plans for lodge headquarters, arrangements with venue managers for club meetings and conclaves, and more, among the correspondents Joe Lightner, Walter Domzalski, J.V. Gentilly, George Linnhauser, Walter Harris, W.R. Walsh, "Lefty" Naylor, and L.P. Bowen; with two member ribbons, I.M.C. programs (one signed by Blackstone), membership cards, blank sheets of letterhead, membership certificate, loose issues of the club magazine Seven Circles, and more. Blackstone formed the I.M.C. after his dramatic expulsion from the Society of American Magicians in the midst of an ongoing dispute with Harry Houdini over the use of an escape trick. Houdini was president of the S.A.M. when Blackstone was expelled.
