ROYAL COUPLE by Gustavo Sereno and Gee Magic (Gimmick Not Included)

In this effect you ask two spectators (ideally a couple) to take a card. It happens to be the queen of hearts and king of spades. They sign their names and both cards are placed face to face on their hands. When they open them, they will realize that the queen and the king are now fused by their hands. this makes a very romantic surprise that the couple can keep as souvenir.
