Have someone select any letter of the alphabet: A to Z. By having them simply sort through the 7 wood cards and selecting only those cards that contain the chosen letter (turning them upside down so that you have no clues), then you will quickly be able to tell him the chosen letter. Inspired by Maurice Kraitchik's 1942 book on Mathematical Recreations. They can be great fun and are quite astounding in how they work. On this set there are 7 letter cards and a header card. They are each 4" x 1.3" made from 1/8" thick alder. They are precision made in Creative Crafthouse's Florida shop and the text is all deeply laser engraved.
