From the Derek Dingle Estate -- hand assembled by Derek Dingle.

An odd backed card is placed in the middle of the deck as the spectator attempts to select it. When he finally selects a card it turns out to be the only regular card left in the deck as all the others now have odd backs. Includes instructions to Derek's Simple Force.

Comes complete with Poker-size (assembled) rainbow deck and instructions. As originally sold by Derek Dingle at his lectures and through Palooka Productions. Very limited quantity.
