The footage also gives us a good look at the exedra on the day of the funeral. What's interesting is it doesn't yet have the Houdini bust, nor does it have the Society of American Magicians mosaic emblem. The bust I understand; it needed to be cast. But one wonders exactly when the S.A.M. symbol was added and whether it was Houdini's idea?
Maybe the origin of the mosaic -- which is beautiful work -- is something the S.A.M. will investigate as part of their upcoming restoration of the grave site.
