So I tried out these maps.
First of all, the maps look gorgeous - incredible work!
I also like those little spots, where my players immediately jumped on, like a half covered stone face on the ground, a small crack in a cliff, where a little dungeon might lurk.
I had some issues with printing it to scale, but the publisher helped me out on the same day I had the issue.
Everything works fine. To printing it to scale do the following (Adobe Reader 10):
You can print the maps into 4 tile pages out of the PDF by adjusting the "Page Handling" tab to "Large Tile Pages" right in the print menu. This should split the map into 4 pieces which you can print out into 8.5x11 maps and assemble.
If you like maps, you will love these!
