According to Tom Interval at the blog Houdini Museum, there is a collection of 5,000 "books, personal scrapbooks, pamphlets, and periodicals" of Harry Houdini's archived in the US Library of Congress. In fact, parts of the collection are in digitized form online. In Interval's words:
Houdini’s personal scrapbooks—all 126 of them—were packed with newspaper clippings, theater notices, ephemera, and countless other items of interest. One such item was a small piece of paper with a simple illustration on it, perhaps drawn by the man himself; underneath, a typewritten caption read, “This figure contains all the letters in the alphabet.”
Cool, right? When a Googling failed to show that no one had yet turned Houdini's idea into a font, I decided to do it myself.
The result: a monospace typeface that defies boundaries.
