Presenting the Cahill-Keyes 1º Globe
World's first and only Earth-globe drawn with a one-degree graticule

(Designed by Gene Keyes; produced by Joe Roubal
as a third C-K prototype)

Why? To show that the Cahill-Keyes one-degree "Real World" map (second image below) bears a high-fidelity resemblance to a globe — especially this one-degree globe — : point for point, geocell for geocell, continent for continent, octant for octant.
