I'll start: The move Marlo called "Tilt" was invented by Dai Vernon and called "the Depth Illusion." It's just a crying shame that "tilt" is a much better name than "depth illusion."
Even Vernon called the move "Tilt." And I've heard many times that he actually received the basic concept from Burling Hull.
Then he proceeded to use the new name he gave the technique dozens (hundreds?) of time over the next few decades and never mentioned Vernon in connection with it again.
That's a pretty sweeping statement. The first time I met Marlo, the topic of Tilt came up, and one of the first things he said was that Vernon had preceded him on the move. He didn't seem to have any qualms about throwing it out there; he's the one who brought it up.
Oh, and that booklet in which he gave Vernon credit? He let it go out of print and never reprinted it.
Meaning...what, exactly? Shall we ascribe mysterious, possibly sinister, motives to every book you've allowed to go out of print? Or should we just assume it was a decision driven by the market?
I appreciate your comments, Richard, about Bill Malone, and agree. I don't think, though, that a great performer can make a bad trick look good. If that happens, I just assume it wasn't a bad trick to begin with...it's just that nobody before recognized what was good about it. Maybe part of what makes a good performer is having that kind of insight.
