Pallbearers Review by Karl Fulves Autumn 1973 The Lynn Searles Issue Page 673 et seq.
Personal Comment: This is certainly no "Cannibal" routine despite the title. This is more a "Visitors" plot. But its a good trick. Easy to do and rather deceptive. Even if you don't do that routine, if you ever need to make a card vanish from a sandwich this is one good way to do it.
