This appears to be a large version of Dotty Domino.
A VERY RARE ITEM!
ONLY A FEW ‘DOUBLE TROUBLES’ WERE EVER MADE BY ALAN WARNER DUE TO THE SIMILARITY BETWEEN THIS PARTICULAR EFFECT AND HIS OTHER, EARLIER DOMINO EFFECT, ‘DOM-DOM-DOMINO’
A large, black-faced domino with white spots is passed behind the performer’s back. When it reappears, THE SPOTS HAVE CHANGED COLOUR AND ARE NOW ORANGE. This move is repeated and the orange spots revert back to white again.
Not surprisingly, the spectators suspect that the domino is merely being turned over each time it is hidden from their view behind the performer’s back. The performer agrees with the spectators that there are indeed orange spots on the back of the domino…and BLUE spots…and GREEN spots…and RED spots! Having said this, he turns the domino around to reveal that the spots are MULTI-COLOURED!
The performer suggests that the spectators may now be wondering what is on the other side of the domino. He then repeats what he said a moment or two earlier… There are ORANGE spots…and BLUE spots…and GREEN spots…and RED spots! THE DOMINO NOW HAS MULTI-COLOURED SPOTS ON EACH SIDE OF IT!
