Sometime in the early 1980s, I believe, I saw on either the Merv Griffin or Mike Douglas talk show a mentalism trick presented by either Glenn Falkenstein or Maurice Fogle. The magi quickly found, from a pile of perhaps a couple hundred disassembled jigsaw puzzle pieces, the one piece that matched a piece freely (?) selected (by an audience member) from a matching assembled jigsaw puzzle.
Does anyone remember this? Any idea who the magi was and if this has ever appeared in the magic literature anywhere?

It was Romark and you can find in the "magick" by Bacom jones and in is magazine # 254....

I hope this helps...
