This is totally impromptu and best of all requires no gimmick. It's taught really well and shown
from several angles. I got a lot out of it during the card selection and replacement part in the
beginning when Kariem Ahmed shows a Lee Asher move.
Yes, it does require some practice in
front of a full length mirror just to get the angles right. Jeans and an un-tucked shirt are ideal
for performing. Great trick!
(Incidentally, buying the download from Penguin saves a few
dollars over purchasing from Magic from Holland because of the currency difference.)
