Mr. Jan Pieter from Netherlands sent me the souvenir sheet issued by TNT Post (Dutch Post) to celebrate the bicentenary of Louis Braille. Twelve stamps (each one face value 44 cents) presenting the braille alphabeth. Each Braille character or cell is made up of six dot positions, arranged in a rectangle containing two columns of three dots each. A dot may be raised at any of the six positions to form sixty-four permutations, including the arrangement in which no dots are raised. This sheet is a tribute to a man who revolutionized written communication for the blind.
