THE BRAILLE ALPHABET
63 characters of the cell in seven lines — 26 letters, the digits, the punctuation and 8 prefixes
Built as a memo rather than a table: the thing worth hanging it up for reads across the room, with the full reference in smaller type below it.
Three sizes in one archive — from a sheet on the fridge to a poster on the wall.
A large dot is raised, a small pale one is not. Under each cell stands what it means in Unified English Braille.
