Dallas Cowboys QB Dak Prescott and Mavericks legend Dirk Nowitzki are each lending a hand to a Dallas-based nonprofit—literally. The newly launched My Hand My Cause has a mission of capturing fine art photos of "the most famous hands in sport, music, movies, art, medicine, science, and more" and selling them to help fund charities and foundations worldwide.
