Copper engraving, 446x604 mm. Beautiful bird-eye view of Bergamo. From "Nouveau théâtre d'Italie". Mortier, a publisher active in Amsterdam at the turn of the century, reprinted Blaeu's 'Theatrum Civitatum...Italiae' of 1663 and added a fourth volume, relating to northern Italy and Tuscany. Likewise, Alberts made changes and inserted his imprint on many maps. Very good example, usual traces of editorial folds, very marginal, with some minor foxing
