An extremely unusual proof state of Du Val’s map of Asia

A rare 'proof' printing of Du Val's map of Asia, engraved by François de Lépine (signed FD Lapointe) in 1664 and first published in Du Val's scarce atlas, 'Cartes de géoraphie', in 1667. However this is apparently an unfinished proof of the 'second' state, 1676, with the original huge island of 'Jesso' removed but without the engraving of the replacement 'Kamchatka' peninsula, leaving the coastline near Yupi unfinished. Korea is still an oval island rather than the corrected peninsula. The title has been updated with the 'Reveuë et augmenteé' and 'au coin de la Ruë de Harlay' added to the address and the date of 1644 removed and not replaced. The cartouche around the title has been heavily re-engraved. We have been unable to find another example of this state.
