You are welcome to print out and use this map as you will. The only restrictions are that you not re-use the work without attribution.

First, let me tell you how amazingly mind blowing this map you made is - it's pretty amazingly mind blowing indeed. Not to mention it's the only WoT map that has appropriately epic dimensions, given the epic proportions of book series. Second, would you mind me using this for wall poster (properly framed and all that jazz)? I was thinking I'd take a photo onec it's done and paste it on Sanderson's/WoT FB, link to this page included. What say you?
Sorry for the late reply. You're free to use the map as you've described. If you look closely, there's a creative commons license on it, so you can do anything within that license without having to ask permission. Enjoy!
Seriously, is there any possibility of you making/printing this as a poster? I would absolutely adore it, and would happily pay for it!! If not, is there any chance I could get a high res version to get printed out at my local printing shop? Again, I would happily leave you some type of payment or donation in order to have this as a poster on my wall. Its wonderful.
You're welcome to print it out, though the largest version on DA is the native resolution. It's pretty big. Having printed out some of my other maps poster size, I can tell you they come out really nice, quite frame-able.
