This map comes from a richard andrees atlas from 1887.
It is folded.
At the fold, the two pages are 10 cm apart.
On the back on each half a map of sachsen and brandenburg.
There is the photo of the cover page to justify its origin, it is not sold with it.
This card is shipped in a large reinforced envelope.
The format given is that of the unfolded card.
The card support is relatively thick, therefore good support for possible framing.
Several maps available.
