DEBIERE, Arnold (1878 ? 1934). Arnold DeBiere's Multiplying Billiard Balls. Circa 1915. Included are 15 solid balls, two inches in diameter, made of celluloid or a celluloid-like material and five shells (white, gold, silver, yellow, and red). The balls are in eight colors: white (1), silver (5), gold (3), green (1), blue (2), red (2), yellow (one, faded), and royal purple (3). The shells cling to the balls securely but may be dislodged with relative ease.Also included are three expandable ball droppers with machined aluminum clips attached to their exteriors, owned by DeBiere and likely manufactured for him by Jon Martin. Length of each 11".DeBiere was well-known for his manipulative magic and made a specialty of the Billiard Ball effect. He developed several special moves in his routine, and devised (with Jon Martin's help) mechanical gimmicks that aided a trick that otherwise relied on pure sleight of hand. These balls, obtained by DeBiere by the Davenport family, are lightweight and far different than the standard props used during his lifetime (most Multiplying Billiard Balls were made of wood, with wooden shells).
