The spherical globe with metal poles is covered with black slating material and sits loosely in a copper-finish metal cradle stand. The horizon has an engraved paper calendar that is calibrated for miles, degrees, and hours, and is supported by four quadrants on a circular molded base.

Globes coated with slating material have been produced from the mid 19th century on as educational aids for the study of geography, so students could practice drawing maps in chalk on the surface.

This example has flying data printed on the horizon: “Estimated Jet Airliner Cruising Speed 600 Miles per Hour. Estimated Propeller Airliner Cruising Speed 300 Miles per Hour.” This data was probably included to incorporate aviation and travel themes -- popular interests reflected in globe manufacture in the mid 20th Century. Perhaps this data was also included as a way to include mathematical calculations into lessons.
