Feel-A-Color - Royal
This sensational trick can be done blindfolded - literally. The magician displays four colored cards, and hands them to the spectator. With his back turned, the magician instructs the spectator to select one of the four cards, and then place all four cards on the table.
Even with a blindfold, the magician can then discern which of the four cards were selected - apparently by sense of touch alone. Easy to do. Full secret and professional instructions included with all necessary props.
