BLIZZCON 2011 DIABLO WORLD OF WARCRAFT KEY ART **SIGNED** POSTER 1/1? VERY RARE!

This Poster was signed by developers of the respective games at Blizzcon over a decade ago. This is an EXTREMELY RARE piece of Blizzcon history and the poster is in excellent condition. This may be the only signed Key Art poster in the world as no one at Blizzcon was asking developers to sign posters at their respective booths.
