Quarterly Returns by David Devlin
A card is selected and signed. The card is then cleanly torn into four separate pieces. The pieces are then placed between the fingers ala The Multiplying Billiard Balls, and the hands are otherwise empty (they really are!). The pieces are then gathered up one at a time. Each side of each piece is clearly shown. The bundled pieces then instantly pop open in a "flash". The card is fully restored and given to the spectator to keep as a souvenir.
