Giant Divination Box. Circa 1870. Oversize version of the thought-reading effect; six numbered blocks are arranged in a wooden case and the lid is closed, yet the magician instantly knows the order of the blocks. He uses an empty metal tube to give him “x-ray" vision and peer through the wood. Mahogany case, length 15 3/8". With gimmicked tube and matching “front" (these usually lacking). An early, large, and attractive example.
