Please note The 1950s were a pivotal period in Hans Hartung's career, marked by a profound change in his visual language, with a gestural, free and vigorous style. He explored new expressive forms, often using diverted tools - brushes, combs or sprayers - that allowed him to vary the effects of material and rhythm. It was a period characterised by intensely rhythmic work, in which the gesture - rapid, sometimes impulsive - became the very expression of the painter's inner tension and energy.
