Purtroppo, questa descrizione non è stato tradotto in italiano, in modo da trovare a questo punto una descrizione inglese.
The characteristic appearance of the DUO map image is achieved only after a 24-stage printing process. The brilliant colours when illuminated, and the political map's colour harmony are complemented by an unsurpassed wealth of up-to-date information (cold and warm ocean currents, mountains and oceans when illuminated, shipping lanes, railways and airline routes, and much more besides). The map image is produced by hand using traditional techniques.
