What's the value of?...

[Zingela]

I'm currently in the middle of packing and sorting for a move, and while going through my collection I found this signed print for The Witcher:

It's roughly 4x6 and has a tiny amount of bending on the corners.

The back reads: "This is a limited edition signed and numbered print of artwork by Damian Bajowski produced especially for the GameStop 2007 Managers Conference." Any insight would be appreciated.
