Seeking historical map + modern reference map

[Markus Neteler]

Hi,

to illustrate the GIS capabilities of georeferencing scanned historical
maps to a modern reference map, I am seeking a sample pair.

Is anyone willing to "donate" it (be in public, be privately)?
As European citizen I have the wel known problems to get
such material...
Also a non-European example is fine!

thanks in advance

 Markus
