Kept in a glass case for more than four years, an original model Nintendo DS bearing the autographs of some of Nintendo's key players (and two literal key players) is being auctioned off by its owner to raise money for the Red Cross disaster relief effort in Japan.

The red Mario Kart DS promotional system is signed by Mario's creator, Shigeru Miyamoto, along with composer Koji Kondo, Zelda series chief Eiji Aonuma, voice of Mario Charles Martinet and Martin Leung, a pianist who performs with Video Games Live and rose to fame thanks to a YouTube video of him playing the Mario theme blindfolded.

Its current owner has vowed to donate 100 percent of their profit from the auction to the Red Cross and provide proof of the donation to the winning bidder. As of this writing, there are six days left to not only get your hands on a rare gaming collectible, but do something good for your fellow man in the process. Visit redcross.org for information on donating directly to the relief effort.
