It's in the link in the first post, not among the other files.
Well, if you mean the large thread started by Ilya, there is a link to the BGG image of the map, the image ID is 858015. That one is the one I meant is low resolution. If you printed that one out board size it would be pixelated. I must be missing something. In the comments for that image, someone points out a mistake, and Ilya puts a link to the corrected file, but that link is broken. Hopefully someone can steer me right.
