It was the only American globe to show relief on both continents and ocean floors. It was not customary at the time to include ocean bottoms in relief. The relief was made of plaster then painted various colors to indicate elevations. In 1928 the firm produced its first physical globe, edited by Professor J. Paul Goode of the University of Chicago. This was a 16 inch globe.
Isotherms appear in red and blue.
It was basically a cradle mount with a horizon ring. The horizon ring, however, was hinged so that it could be lifted to show the path of a satellite around the globe. The mount itself was of metal. It featured a gimbaled mount involving two movable metal rings that could be used to indicate the path of a satellite. Around 1960 Rand McNally was producing globes mainly for home and library use.
