Are old globes worth anything?
Similarly one may ask, how old is a globe?
The first known mention of a globe is from Strabo, describing the Globe of Crates from about 150 BC. The oldest surviving terrestrial globe is the Erdapfel, wrought by Martin Behaim in 1492. The oldest surviving celestial globe sits atop the Farnese Atlas, carved in the 2nd century Roman Empire.
Similarly, how do you clean an old globe?
To clean the globe, wipe off the entire ball with a clean, dry, soft cloth. Stay away from sponges or paper towels since the texture of these items may rub off the map image or scratch any other surfaces. To clean the pedestal, wipe off the stand and any other metal pieces with a damp rag.
Traditionally, globes were manufactured by gluing a printed paper map onto a sphere, often made from wood. The most common type has long, thin gores (strips) of paper that narrow to a point at the poles, small disks cover over the inevitable irregularities at these points.
