Paris: Librairie National d'Art et d'Homme, G. Van Oest, 1926. First Edition. Three volumes; folio (33cm.); publisher's navy blue cloth, gilt-lettered spines, top edges gilt, others untrimmed; vi,67pp. & 274 collotype plates; additional 14 plates of maps and plans, all but one folding; frontispieces in each volume. Boards very gently shelf worn and corners bumped, upper cover of Vol. I dampstained; some plates starting to separate and one plate (no. 121) loose, not an uncommon occurance as the textblocks are too heavy for the bindings. Still, quite a nice, better than usual set in the original binding. The collected photographs taken by the Swedish art historian and sinologist during his stay in Peking in 1922.
