As most of us know, Houdini once billed himself as "The King Of Cards"... and this videoclip

shows that he really was quite adept at some of the standard card flourishes. I remember, too, one of the books--_Houdini's Fabulous Magic_ by Walter B. Gibson and Morris N. Young--included a description of the boomerang card. I actually was able to learn how to scale and boomerang cards based on the details described in the book.

Yes, Houdini was very adept at cards. David Bamberg mentioned this in his book Illusion Show, "He proceeded to do a series of juggling card tricks that took my breath away. Spreading the cards on his arm he threw them into the air and caught them as they came down. He had a brilliant routine which he finished up by dropping the cards in a stream from his right hand and catching them with the same hand just as they reached the floor."
