A card is selected by the spectator and signed before being lost in the pack. You draw a black line on the top card of the deck before making the line disappear only to reappear on the back of the psectators signed card.
A clever gimmick is supplied and this trick is easy to perform, you’ll only need a little practice.
Also included is a link for online instructions from Red Dragon, these are in Italian but are still easy enough to understand just by following the video.
You will also need a regular deck of red Bicycle cards for this trick.
