A map of the Billung March/March of the Billungs (German: Billungische Mark, Billunger Mark, Mark der Billunger) around 1004 CE.
The map is derived from a vectorised version of one found in Professor G. Droysens Allgemeiner Historischer Handatlas, which was published in 1886 by R. Andrée Plate, and is now in the public domain.

Note that while it uses the same scheme as standard location/locator maps, this map technically does not conform to the standard, as it is not in equirectangular projection. Therefore grid lines for latitude and longitude are included on the map.
