There is a photo of this sheet music in the Ken Silverman book, Houdini!!! The Career of Ehrich Weiss, credited to the Morris Young Collection. But I don't recall ever seeing one for sale and I've never seen it in color. It's a beauty and really speaks to Houdinimania of the day (I can see this selling in Boston). I'd love to hear the tune itself.
Thanks to Kevin Connolly at the Conjuring History Facebook group for the find.
UPDATE: Here's the winner of this mega rarity; the mighty Arthur Moses! Says Arthur, "Been looking for that for 20+ years."
