A vintage pull down school chart made by German firm "Justus Perthes, Darmstadt". The chart is titled "Die Atmosphare der Erde 4" and was likely part of a series of geography based charts used in educational settings, designed by Prof Dr Rudolf Geiger.

Although the chart is in both German and English, there are labels in Dutch on the back, likely dating back to their school days! Meaning that the charts likely originated from Holland.

The chart is on a pull down system made by Danish firm Richter, with a heavy duty wall hanging attachment meaning it's ready to display. It can be rolled back up and clipped into place while still mounted on the wall, for ease of access and storage.
 
This would be a statement piece for your home.
