This effect uses a variation of The Invisible Wand
by Larry West and Al Cohen, with moves by Shigeo Futagawa and
Francis Carlyle. Qua-Fiki has some pictures of famous super
heroes, but that mischief maker, the Invisible Man, has made them
all invisible, like himself. Qua-Fiki shows all the cards blank
on both sides as he searches for the card containing a photo of
the Invisible Man. At last it turns up, but of course it looks as
blank as the other six cards. By applying "Logical
Magic" to the problem, Qua-Fiki finally makes the super
heroes show up. Then he proceeds to show the greatest super-hero
of them all on the last card... himself! As an added optional
bonus (not shown on the video) the Invisible Man can also appear
on the blank card, if you wish.
