Clarke & Clarke Metropolitan Hatoum Slate Wallpaper. Hatoum has rhythmic swirls that undulate around with dramatic effect. Evoking ideas of agate, marble or rock formations, the design depicts explosive, abstract brush marks, creating a piece of immersive contemporary abstract art, from floor to ceiling. With a beautiful tactile hopsack-texture, a soft raised effect is created, further lending to overall impression of the design as a display of wild, circular, organic forms.
