When our Prince is playing tennis with the Marquis and falls into the spectator's area, he is surrounded with couriers and stuffed with hankies. He climbs out, notices the hankies and starts to pull some out. As he looks to Margritte for the ball, some of the hankies are magically back where they started. When he approaches her, the hankies are gone again. Where can I get some magic hankies too?
