This publication showcases an easily overlooked byproduct of artistic production: the painter’s rag. In its hybrid role between object, image, tool and trash, the painter’s rag documents the painterly work process, and functions as the painting’s counterpart, freed from any intimation of deliberateness. With color reproductions of 39 vivid painters’ rags and essays by Sophie Jung, Hanne Lippard, Christian Struck, and Cecilia Valenti.
