A collapsible Betts's New Portable Terrestrial Globe made by George Philip & Son, after the original patent taken by Betts.
This globe is opened and closed by an umbrella mechanism, to allow for ease of transport and originally would have had a box. Although sturdy when opened the nature of its operation no doubt led the silk on many to become damaged. These globes are relatively rare due to the fragility of the silk and the stress the operation of the globe causes it. Circa 1880.
Size opened is given
