Large Geological map

Very large vintage school wall map from the sixties / seventies of the publisher Justus Perthes Darmstadt. The subject is the geology of the earth. At the top and bottom is a black wooden dowel with a leather strap on either side. The condition is good considering the age, color may have become somewhat blurred by the influence of light, see also the detailed pictures. The dimensions are 210 cm wide and 137 cm high.
