Tables for Determining a Globe’s (or Map’s) Age
One way to determine the age of a recent globe (or world or regional map) is to look at the political boundaries: if you know when boundaries changed or when countries became independent, for example, you should be able to zoom in on the year of production if it isn’t printed somewhere on the map or globe. Both globe maker Replogle and map and globe maker Cram have compiled tables to help you figure out the age of your globe (or map): here’s Replogle’s; here’s Cram’s (PDF). Via Map the Universe.
