According to Barry, "There are many pages of newspaper clippings written by Houdini or mentioning him, and his crusade. There are also pages of notes on floating trumpets, sittings, spirit guides, a list of birthdays, and the like. The clippings come from the defunct Philadelphia Record. They mention Houdini's engagement at the Walnut St Theatre in Philly."
Barry sent along the following page, which clearly shows the depth of hatred some Spiritualists felt for Houdini during his lifetime. Vicious stuff.
Thanks, Barry, for sharing this fascinating snapshot of the time.
