Pollock experimented with many types of paper throughout his career, from rough cardboard to the finest Japanese paper. The handmade paper he used for this drawing was chosen for its exceptionally porous and textured surface, which gives his marks an almost blurred quality. The lines and forms in this drawing are also notably centralizedthey appear to swirl inward—signaling a shift from slightly earlier compositions that seem to spill over the edges. This is one of Pollock's last drawings.
