An oldie but goodie, from Warren Stephens. This is the the self-contained gimmick that you add to your deck to cause a the selected card to slowly crawl out of the deck. No threads or external hook ups. As this is from the 1970's when everyone used Fox lake cards, this is a bridge size Fox Lake red back gimmick.
The gimmick works fine, but since it probably does not match your favorite working deck, I offer it as a collectors piece. Original gimmick card and instruction sheet.
(If you want the same type of gimmick that matches a Poker size Bicycle deck, search our ebay store for Spook Cut -- the current version of this exact same trick.)
