European. Circa mid-1800’s. Four, 4 ½” square wooden plaques are shown, each containing two small paintings of various scenes. From the eight possible selections, a spectator chooses one and places the plaque in a small wood and paper-covered box. The remaining plaques are hidden from view. Setting the closed box on the table, the mentalist proceeds to describe the unseen picture in detail. The box is opened and plaque shown to confirm the mentalist’s description. Early use of magnetics that allows the mentalist to “see” what picture was chosen, unbeknownst to the spectators. Condition: Very good. Some wear from age. Rare.
