Glass bell with clapper and upper ring sounds out answers to questions posed by the audience. It rings once for "yes," two rings for "no" despite being untouched by the magician as it hangs from a black metal wand. Nickel plated elements, wand working well. Very mild wear, else in very good condition. An attractive, delicate, and deceptive vintage conjuring prop favored in the era of spiritualists at the dawn of the twentieth century.
