Their collaborative relationship is unique: one paints a painfully detailed vision of the victims of the atomic blast; the other conceals the carefully delineated brush strokes with a grey-black ink “wash.” The first artist restates the specifics of the image; the second re-conceals. Through the repetition of this process, the work emerges.
