H.A.M. van der Heijden's fascinating book on Leo Belgicus maps is only the second reference to cover the topic, after Tooley's long out-of-print Leo Belgicus, An Illustrated List (Map Collector's Circle #7). It complements and expands on Tooley's work, covering more maps with more in-depth publication information and black & white illustrations. This is an essential reference on one of the most enduring works of decorative cartography. 113 pp. Soft pictorial covers.
