A Rand McNally Geophysical Globe initially arrived at the Adler Planetarium on August 14th, 1961 to be part of a temporary exhibition. While the exhibition only ran for about two months, 28,000 visitors came to see the globe. Rand McNally was interested in the Adler's existing 1940 scale model of the moon (WRK-3) and asked for permission to produce copies of the moon, in exchange for gifting a geophysical globe to the Adler (it appears this was a different globe than the one on display in 1961). This new geophysical globe was built in 1959 and delivered to the Adler Planetarium in February 1963.
