Between the Clock and the Bed features a cross-hatch pattern, rendered largely in purples, greens and oranges. At the lower right hand corner Johns deploys yellow, red, and blue, in a nod to a painting of the same name by Edvard Munch. Art historical references such as this abound in Johns’s work: he regularly quotes himself and others. An artist of tremendous depth, Johns has produced a body of work as densely layered with materials—paint, wax encaustic, charcoal, and ink, among others—as with images.
