What better way to celebrate the annual Mass Effect celebration known as N7 Day than by purchasing a piece of art used in the creation of your favorite virtual space epic?

A quick trip to eBay will reveal a signed, original portrait of a Salarian. Not just any alien doodle, this image was created by BioWare artist Matt Rhodes as concept art used in the creation of the overly-logical extraterrestrial race.

The current high-bid for the sketch stands at $207.50, with nearly 72 hours left before bidding draws to a close. All proceeds from this auction are earmarked to benefit Child's Play, a charity that helps ease the suffering of sick children by outfitting hospitals with entertaining, therapeutic gaming hardware.
