Congratulations, Eef. I hope i will have more informations soon.
About the word condominium Spain/France i think is not the best word, 
at least for the spanish side: the spanish government never had any 
right over Andorra: since 1276 the rights over andorra were owned by 
the Foix county ( and after, by the french republic ) and the bishop of 
Urgell. So, its curious that there are two coprínceps: a priest and 
a president of a republican country. We could sepak of condominium 
just in geopolitical terms: Andorra has survived as a independent 
contry because his position between two strong countries.
More about Andorra: ive found a 1:50.000 map of the border based on 
the spanish army cartography, but i cant open it. I think its 
necessary to have a specific program like ARC/INFO, Arc View, Arc 
Explorer, ERDAS, Mapinfo, INTERGRAPH ... Could anyone open it and post 
it as a GIF, BMP, JPG
?
