http://www.georgeglazer.com/globes/novelty/plastersphere.html We have a plaster sphere mounted in a box that is clearly for measuring something, but we're not sure what. We've put up some pictures and a description on the web page above. We decided to turn to this list to see if anyone knows the answer to these questions: Does this have anything to do with geography (e.g. is the meridian line the Prime Meridian?), or is it related to something else entirely, such as geometry or optics, given that the corners are marked with the words concave and convex? When was it likely made?
