Geographicus Rare Antique Maps is a specialist dealer in fine and rare antiquarian cartography and historic maps of the 15th though 19th centuries. A large portion of their inventory of authentic antique maps is online at their website. Geographicus Rare Antique Maps donated their collection of digital images of maps in March 2011. The collection consists of more than 2000 old maps.
How to help? 
On upload the files are placed in Category:Maps from Geographicus to be categorized. You can help by replacing this temporary category with relevant real categories. You probably want to enable a tool like HotCat for quick categorization.
Matching cartographers 
Every file contains a link to a cartographer at the Geograph website. This needs to be replaced with:
- The name of the cartographer or a Creator template
- Possibly a category for the cartographer.
