Clarke & Clarke Exotica 2 Congo Forest WallpaperClarke & Clarke Exotica 2 Congo Forest Wallpaper. Named after the tropical rainforest in Central Africa, Congo is a densely painted design with stunning depth, using dramatic deep colours. With all the qualities of an oil painting, this wallpaper stands out as dark and mysterious, like a visual from the Joseph Conrad novel, Heart of Darkness, the bristling leaves bringing a calmer sense of nature to the foreground. * Brand: Clarke & Clarke * Wallpaper
