Anverdi Spirit Bell. Leiden: Anverdi, 1970s. A bell, isolated on a thin plexiglass platform, is repeatedly struck by a hammer hinged to a clear plexi upright next to it, as if the striker were being moved by an invisible hand. The bell rings out answers to questions (once for “yes” and twice for “no”), reveals the identity of chosen playing cards, or rings out thought-of numbers. 5 ¾ x 7 ¼”. New electronics and remote; very good working condition.
