I am selling the Late 19th or early 20th Century Philips' Planisphere Reference Tool.

It measures about 10" in diameter.

It is marked "Philips' Planisphere showing the principal stars visible for every hour in the year. 

The reference tool is made of heavy cardboard.

It has additional information on the back.

This piece is in good usable condition with light wear to the edges of the cardboard, as shown. 

It still spins as it should. 

I am always willing to combine shipping to save you money.
