A spectator thinks of any card in an imaginary pack, making a note of card on slip of paper which he folds and retains, unseen by the performer. 
 
Performer now removes a pack of cards from its case and runs through them, removing a single card. 
 
It proves to be the chosen one!
 
Condition Notes:  In very nice condition, this deck also makes an incredible display piece if you choose to showcase it. As with many vintage cards, a touch of fanning powder may help restore their smooth handling for performance use.
