‘…above the grey land and the spasms of bleak dust which drift endlessly over it, you perceive, after a moment, the eyes of Doctor T. J. Eckleberg…[his] eyes…are blue and gigantic – their retinas are one yard high. They look out of no face, but, instead, from a pair of enormous yellow spectacles which pass over a non-existent nose…his eyes, dimmed a little by many paintless days, under sun and rain, brood on over the solemn dumping ground.’(p.26)
