A study with a dark wooden table, two wheeled chairs and shelves of stacked books, drawn in loose graphite hatching on cream paper. The square seat cushions of the two chairs and the block-like book stacks on the table carry the finder squares, with their black frames and pale centers. Dense black shading on the shelves and table forms the dark modules, while the pale floor and wall hatching supply the light ones. Strong contrast between solid black blocks and sparse line work keeps the pattern clear across the whole sketch.
