A spectator makes two signatures on the face of a card (bottom and top), the illusionist signs the center of the card, with surprise he makes his mistake showing that his signature was in the opposite direction to the signatures of the spectator, placed with two Clips the letter on your tie and magically (zig zag style), separate the middle part of the letter by inverting the signature and repositioning it in the correct direction with respect to those of the viewer. At the end, he delivers the recomposed and signed letter, as a souvenir.
