Peake’s illustrative style can fall into three categories. The first using clear and continuous line which outline the objects, simplistic but expressive, the use of white space equally important to the effectiveness of the drawings and composition. The second is probably his most iconic. The cross-hatching gives the drawings their tonal value and a depth of atmospheric power; these are often described as dark and morbid. Many of the figures in these examples are not outlined solidly. He uses small strokes in various directions, sizes and spaces to give the effect of a solid silhouette. The third category was predominantly executed with the Chinese brush, giving the images a looser quality, though the variation of marks used for texture were just as extensive as his work with pencil or pen and ink. As colour printing was still very costly at the time, nearly all of his images were produced as black and white images.(7)
