Vintage Simplified Planetarium / Tripensee

A simplified planetarium featuring only the earth, moon and sun with a manually-operated metal bar for rotation. The 6″ yellow plastic sphere represents the sun raised from a pedestal and round base segmented by months. The metal Earth orb is partially shielded by a semi-circular disc representative of the universe. The moon, smallest in scale, is represented by a two-tone sphere.
This device is not a true planetarium as only the earth, moon, and sun are present. However, it is complete, as issued.
