The Elementary Planetarium,Only by Trippensee, Saginaw, Michigan, U.S.A.
This planetarium or tellurium was used to show the workings of the sun, moon and earth. The lighting is located in the yellow sphere and represents the sun. The axis of the stand rotates and drives the chain that triggers a rotating movement of the arm, with earth and moon orbiting each other and together around the sun.
Complete and original with everything included. The tinplate globe is bright and undamaged.
Electrically powered. Unable to test due to American plug. Appears to be in order.
