LOS ANGELES (AP) — The founding document of Alcoholics Anonymous, known to adherents as the "Big Book," sold at auction Saturday for $2.4 million to billionaire and Indianapolis Colts owner Jim Irsay. The auction house Profiles in History announced the sale of the manuscript with handwritten notes from the group's founding fathers.Irsay told The Associated Press he plans to build a special display for the manuscript and display it for several months a year at Alcoholics Anonymous' headquarters in New York. He says he attempted to buy the manuscript when it was up for auction several years ago, and he is thrilled at the opportunity to share it publicly.
