if this is what you are talking about
http://www.boardgamegeek.com/file/info/25840
then yes it was made from a version of IL’s (Imperious Leader) AARHE map
Exactly, that was it !
He printed it as a single map and it was the size of the OOB AA50 map, approximately.
I’ve been downloading a couple of PDFs from jeffderstroyer’s link (thank you, thank you!).
AA50 Final phase1 copy.pdf
AA50 basic version copy.pdf (from 12/01/2008)
At first glance, I can’t tell any difference from them, apart from the file size.
My first idea is to print it as a single map.
If that is very costly, I don’t know.
I can’t see many advantages of tiles over my OOB map.
Anyway, thank you very much for your offering !
