Histoire de Justine ou Les Malheurs de la vertu [avec] Histoire de Juliette ou les Prospérités du vice

Later edition, the sixth according to Pia, one of the very rare de luxe copies printed entirely on China paper (unknown to Dutel) and enriched with a suite of plates printed in red (also on China), not mentioned in any bibliography. 
This copy has all 104 illustrations (44 for Justine and 60 for Juliette) and the entire suite printed in red.
Contemporary half cherry red shagreen over marbled paper boards , spine in five compartments, covers blindruled, top edge gilt.
A few very tiny spots to text volumes and edges of plate volumes, not serious.
An exceptional copy with good margins on China paper with the complete set of plates and a further set printed in red.
