The page consists of three separate geometric cubes described by Houedard as "from a series of battledores: poems constructed from complete alphabets." Handwritten documentation next to the upper cube states "suggest using 3 different weights all lower case" and the cube does illustrate three different pressures on the typewriter.The two lower cubes are made with red dots. The left one is for vowels and the right one is for consents. Battledore is a badmitten racket. -- Source of annotation: Marvin or Ruth Sackner.
