"And in A Lithograph in White Line, the lovely modelling of the slumbering Renoiresque woman is superbly set off by the vitality of the Symbolists lilies, curling out of the darness behind. Technically, this print represents one of Shannon's most original contributions. The skilful use of white line to create the patches of light which so subtly animate the final print, ensures that it ranks aso one of the outstanding achievements of late nineteenth century English lithography" page 14 of the preface by Fenella Crichton.
