Rabbit Trap. Paris: Voisin, ca. 1880. Spring-loaded double trap door, intended for secret use by a magician to effect the vanish of a rabbit or other large object. 9 ? x 7 ??. Two Voisin hallmarks. Uncommon. At one time common accoutrements used by many a magician, these traps ? and others, of varying designs and functions ? were part and parcel of nearly every magic supply depot?s inventory. Surprisingly, despite their popularity, few examples have survived to modern times.
