A 18in dia. C1930's Project-Problem Globe by Denoyer-Geppert Co.

A rare and early example of a Project-Problem globe or more commonly referred to as a Military globe, for it's use in training by the military during WW2. This early Project globe does not have the metal Denoyer-Geppert label that will adorn later models but a printed label of the manufacturer and patent no. on the globe itself. The globe has a brushed on slated surface and the unique twin semi-meridian is spaced to allow a piece of chalk to be inserted, aiding in drawing more accurate longitude and latitude lines. Later Project globes will just have the single meridian. This type of Project globe was preferred over the regular slated globes as it had the hand drawn outlines of the continents. Still the theory of the actual use of chalk by pupils on the globe takes advantage of the strong memory value of muscular action applies.

The actual patent no. of 1894854 was applied for in 1931 and granted in 1933. The patent was actually for the mount and the unique meridian that was specifically designed for use with Project Globes. Note the more vivid blue color of the globe as opposed to the more gray blue of the 1957 Denoyer-Geppert slated map in the background. The hollow metal orb is mounted on a telescoping stand that can reach a height of 6ft.

The condition of the globe is good with some loss of the slated paint as shown in picture no. 4 as well as two small indentations, one in the same area of the loss and another below it. The globe has no rust but minor scuffing. All parts are in working order.

Industrial in design of this globe makes an incredible architectual statement!
