This overlay of the painting shows our Necker cube in View B or the blue-is-in-front view. We are looking down onto the top as well as the bottom planes of the cube, creating the foreground in the painting, The area in light blue follows a plane that goes back in space from the front edge of the picture A to the edge of the spotted drapery B. The front figure leans back into the space and one feels she looks up into the face of the figure behind. (-> #7)
