London: the society, 1900. Volume xv: viii, 204 [nos. 1,2], 565-724p. [no. 6]. Volume xvi: viii, 501-766 [nos. 5, 6]. NB, whole issues (numbers) appear to have been left out! a substantial tome nonetheless with excellent unmolested maps. Find vignette photographic illustrations and numerous folded maps in colors, some quite large, cased into black quarter-calf boards gilt, text edges tinted red. Spine is somewhat abraded, possibly from storage, hinges, textblock and maps are in splendid shape and appear uninvestigated except for one tiny tear we see where one particularly sizeable map is stubbed in; facing the larger maps, adjacent leaves are foxed because exposed to air. Very sound but -as noted- incomplete.
