Detail - 1931 Spinner motion lamp
Colonial Fountain (1931) (Samuelian Book, Pg. 22 left)

Originally this motion lamp was used to grace the top of a console radio, giving the radio listener something visual to enjoy.

This lamp is made out of cast iron and glass. It is 12" long and 91/2" tall.

The animation is of the fountain flowing up the center and down the sides, and water rippling in the foreground.
