By one of the great scholars in cartography, this is a must have reference for any collector of Blaeu's fine maps. It contains fascinating details on the map, his firm and the 17th century map trade. First Edition; pp. [vi], 114, 12(index); 28 illustrations (several in color), appendix, notes, and index. Hardbound in imitation white calf printed in gold & blue. A very good copy.
