I posted this awhile ago and with the recent way of kings leatherbound edition kickstarter I realized I never got an answer to this. Any of you light eyes know how to tell the printing edition?

My wife very much surprised me with the dragonsteel edition of well of ascension. She was a little shocked however when I told her that it didn't cost 100 it cost 300 because now we need the other two. But anyway my question is how do I tell which printing it is? I didnt notice anything obvious on the publisher page. Just curious. Figured you guys would know. Thanks.
