Spirit Clock Dial. New York: Martinka & Co., ca. 1900. Glass dial with gilded Roman numerals sits on a fancy cast nickel plated stand with rope-twisted metal upright. A nickel-plated hand sits at the center of the clock and is spun by the performer, stopping uncannily at any number called for, revealing thought-of numbers, answering questions (pointing to the number 12 for ?yes? and the number 6 for ?no?), or identifying selected cards. Gilt numerals (paint rubbed). Height 36" inclusive of stand. A handsome, large, and early example.
