Im currently filming a mentalism card routine in which I use a peek but have no idea who created it. I need help crediting the move, Ill explain it below
You dribble the cards from your upper right hand to your left hand, the spectator shouts stop. You secretly glimpse the lower card of the upper packet by slightly orientating the left index towards yourself.
I think I first saw the move on James Brown 'fancy a pot of Jam' which I no longer own. If anyone has any ideas please let me know
