Monkey in the Middle

(A SUPER CLEAN SANDWICH EFFECT, NO DIFFICULT SLIGHT OF HAND IS USED.)

EFFECT:

A Card is freely selected from a blue backed deck, the selected card is signed on the face by the spectator for a better impact. Signed card is lost in the deck. Performer introduces 2 red backed cards  (say one is ten of hearts and other one is jack of spades). These 2 cards are freely examined and then placed face up on top of the deck by the spectators. Without any suspicious looking moves, performer waves his hand or snaps his fingers to make the magic happens. Top 2 face up cards are now spread cleanly . Now a card is seen sandwiched between the face up pair! Sandwiched card is removed and turned over. It is the signed selection!!
