This is the first picture postcard to display the Earth's rotation truly three-dimensionally. See the borderline between reality and picture disappear, as you watch our planet appear to spin, in your hands, seemingly within easy reach. A fascinating effect on a perfectly flat display: This postcard is just 1 millimetre thick, thanks to the patented True-3D technology. A great keepsake, or alternatively an equally impressive greeting card (standard postage). This postcard is not an embossed map, it is perfectly level. You cannot feel the shape of the planet. The three-dimensional impression is solely achieved by means of a special printing process. Thus you do not need the otherwise usual red-green glasses, either. Specifications: * True-3D effect * Sense of depth: about 2,5 cm * Lenticular foil (PET), about 1 mm thick * Weight: about 14 g * Reverse: postcard layout
