Copper engraving, mm 430x525. Famous perspective plan of the city of Marche taken from “Nouveau théâtre d'Italie ”by Pierre Mortier (1661-1711), who was a very active publisher in Amsterdam in the early 18th century: among his main labors was the reprinting of Blaeu's “Theatrum Civitatum...Italiae” with the original addition of a fourth volume, relating to northern Italy and Tuscany. Likewise, Alberts made changes and inserted his imprint on many maps. Nice copy, usual traces of central editorial crease, marginal.
