Comments: From the introduction: "Many standard playing card 'moves' are possible with Jumbos, though, obviously, because of their size, the accent must be on subtlety rather than manipulation. The performer should make the most of the many opportunities for comedy, inherent in the very use of cards of such an unusual size. The very fact of asking a spectator to 'shuffle' such a pack, is funny in itself ... and, where it suits the performer’s style, no opportunity should be lost, to allow the spectators to 'mix' the cards."
