Doc Daley’s Last Trick has been worked and reworked by many of magic’s greats...and with good reason! This classic transposition between two pairs of cards is arguably one of the most magical moments you can create for a spectator. Now, award winning magician Jon Allen, has created perhaps the fairest and cleanest method to date! You openly display two pairs of cards. No funny moves or displays, just four cards. One pair is placed in the spectator’s hand and one pair is held by you. In an instant, the two pairs in your hand change places with the cards spectator’s! The audience sees your two cards just before the change and it looks like REAL magic. DOUBLE BACK is a powerful piece of card magic. It just doesn't get any more direct.
