Joining “The Master” Air Jordan 12 #DBDOZEN Doernbecher auction is the Air Jordan 12 “Gamma” – which receives the hand painted design by Nike’s Mark Smith.

The “Gamma” Air Jordan 12 includes some of Tinker Hatfield’s custom sketch work covering one side of the shoe, while the other side is autographed. Each #DBDOZEN shoe is presented in a box printed with Tinker’s initial design elements, and individually autographed by both Mark and Tinker.

Check out the full listing on eBay, and remember that all the proceeds will be donated to Doernbecher Children’s Hospital. Stay tuned to Sneaker Bar to see if they’ll be adding any other Air Jordan Release Dates to the auction.
