The map is made by Ole Engh and Johan Gulbrandsen Natrud using the heliogravure technique. The map is delivered in its original size of 60.7 x 50.2 cm. The size with frame and passe-partout is 78.7 x 69.2 cm. Do you want the map in a different size? Just get in touch - we'll be happy to give you a quote for customization."}
