This is quite an amazing item that will predict any number between 1 and 99. It reminds me of a simple analog computer in its workings. There are 8 cards each measuring about 3.2" x 3.8" x 1/8" thick. The cards have a different series of numbers and different windows cut into each card. Have someone select a number, and the card will very quickly and easily identify the thought of number. No math is used during this process.Based on a 1904 set of mind reader cards which likely have not been reproduced for close to 100 years.
Made them out of high quality alder wood and its really a collector quality item.
