Danica Patrick is changing the face of professional car racing. Though there have been female race car drivers before Patrick, none have enjoyed the success or popularity of the petite, raven-haired woman from Beloit, Wisconsin.

Patrick finished fourth at the 2005 Indianapolis 500, came in ninth at the 2006 edition of the legendary race and now, still in her early 20's, looks primed for a long and successful career.

Danica Patrick has hand signed this 16x20 color photograph of her on the cover of Sports Illustrated, which comes complete with a Steiner Sports Certificate of Authenticity.
