The original wasn't quite like the modern version. Same plot, but he only used three cards to find two selections. Ed Marlo started using a four of a kind to find three selections.
thank you so much - that was the information i was looking for!
i went to the magic circle meeting yesterday where person A performed card warp. person B asked who created the effect and i said that it is by roy walton. person B said he had never heard of roy walton, and i said that he is actually quite known and that he also created "collectors" and "out of this world". i was verbally slaughtered for saying that, somehow i confused paul curry and roy walton and the "out of this world" effect. (inexcusable, i know...) definitely my mistake and i was quick to admit it. i also was accused of disrespecting long-time members when i disagreed with crediting marlo with the "collectors" plot. so lots of clearing up to be done...
i am the youngest member in my magic circle (26 years old) and i am also very interested in the history of magic. there is only one effect which i perform regularly without knowing who created it.
it is actually kevin ho who in his manuscript "smooth operations" says that daniel madison introduced him "to the idea of finding cards through the process of finding other cards". that is where i got it from, but admittedly i made another mistake by just mistakenly remembering that someone credited daniel madison with "collectors" - as opposed to "got inspired by..."
sorry for getting so confused, i guess i am just finding it hard remembering all theses names and effects and so forth...
so thank you for clearing things up!
