What Is A Decoder Chart?
Decoder charts can help you decode a certain area of knowledge. They are simple, concise descriptions with graphics on how to understand an aspect of life. They are 18″x 6″ charts that fold into a 6 page 6″x 6″ cardboard booklet, and generally contain special riveted wheels on 4 of the pages. (Dream decoder is a 10 page booklet) The decoders are unique charts. Unlike a large reference book, these charts make the information easy and fun! They have been consistent best-sellers at Expos for decades!
