General Geological Map of the Netherlands, 1975. Scale 1:600,000. Folded colour print, 63x65.5cm (25"x26"), part of set that also includes same size and scale of Applied geology, of b/w print of shallow faults, contours of top of marine Pleistocene, and sheet of geological sections in green folder. This set is in very good condition but is marred by the use of a black marker pen crossing out library stamps, mostly marginal but some in map area showing through from back and is therefore reduced. Does not affect legibility but spoils appearance.
