Vintage Globe / Planisphere With Black Acrylic Casing

Very unique bookend / decorative object / instructional tool composed of a small globe circa early 1990s mounted atop a Miller Planisphere. The planisphere is a concentric plastic disk which, when rotated to the date and time of day, reveals a window of the sky corresponding to what you would see. The stars are in their proper positions, and the constellations are outlined with their names.
The globe / planisphere combo is cased in a black acrylic frame.
Interesting desktop curiosity that is both instructional and stylish.
Very good condition with only small scuffs to the acrylic.
