In Chapter 2 Nick describes for readers the billboard for Dr. T.J. Eckleburg, an eye doctor whose advertisement looms over the valley of ashes within view of Wilson's garage. Described as a billboard featuring two enormous eyes peeking through a pair of equally huge yellow spectacles, the sign is worn and somewhat neglected. The board, perched as it is above the valley, has a certain watchman-like presence that later becomes layered with religious overtones.
