This collection offers models in 8",12",16" and 30" diameter spheres with matching sculptured bases, pedestal bases or floor stands. Only the 16" or 30" diameter spheres are available with tripod floor stand. The spheres are hand-fashioned from the highest museum quality acrylic and the most up-to-date cartography with current country boundaries, capitals, major cities, and bodies of water plus latitude and longitude markings expertly hand silk-screened on the interior surface to look like hand etching. Each sphere includes an information-packed booklet to help you use the sphere in learning more about our planet along with a Certificate of Authenticity signed and dated by the craftsman who created it.
