To win, just submit a digital scan of an original piece of WoW fan art to our contests email, email@example.com, before September 20th (so two weeks from today). It can be whatever you want-- an ingame NPC, your own character, a scene from Azeroth or its history-- just as long as it's original and it's yours. Then, on September 20th, we'll post the winners, and the best Horde piece will win the Horde Art Card set, and the best Alliance piece will win the Alliance version.
We're rewarding art for art's sake here at WoW Insider, so get out those pencils, crayons, paints, or whatever other medium you want to use, and send us a copy of your piece at firstname.lastname@example.org, and you could be chosen as the best Horde or Alliance artist around.
A few rules apply (as always), and they are found right here. The short version: must be over 17 (13 with parents' permission), and must be a US resident (sorry, EU folks, legal's decision on this one). To make things easy, please include your name, age, mailing address, and email address in your email to us, and you can attach your art as a JPG file in your email.
That's it-- good luck! Get us your art by September 20th to win the rare Art Card set!
