Hartung was acknowledged as one of the leading abstract painters in Paris after the Second World War. His prints relate closely to the thousands of brush and ink drawings that he made in 1953-6. Dynamic compositions emerge from clusters of lines tracing repeated gestures. Hartung believed that these forms were comparable to those in the natural world. He wrote: 'Our organic knowledge, whether it is of the flow of blood or of the force which is in a growing stem, finds its parallel, its equivalent, in what we create.'
