Martin Holdout. London: Jon Martin, ca. 1940. Secret device worn on the magician?s arm under the coat which, when activated, shoots from the sleeve to deliver or steal coins, cards, or other small objects in the hand, then retracts out of sight. Hallmarked by Martin five times. Thief unscrews and may be replaced with other devices (not present). Collapsed length 6 ??. Very good working condition. Rare. Sometimes called ?Cardini?s Third Hand,? later versions made of inferior materials by less-skilled craftsmen were brought to market by Max Andrews? Vampire Magic business in the 1950s. As with all of Martin?s props, this holdout is superior in every way, from form and function to overall design. The thief incorporates a card clip and small receptacle that will accommodate billets, coins, or even folded cards, and has a folding lid that swings back-and-forth to modify its function as needed.
