OKLAHOMA CITY (AP) - A portrait of Texas oil magnate and Oklahoma State University megabooster T. Boone Pickens that will hang in the Oklahoma state Capitol has been unveiled.

State officials and legislators joined Pickens and OSU officials and alumni for Thursday's unveiling in the Governor's Blue Room.

Gov. Mary Fallin says the honor is ``probably long past due'' for someone who exemplifies the spirit of Oklahoma.

Pickens grew up in Holdenville and graduated from OSU when it was Oklahoma A&M. He's donated hundreds of millions of dollars to the university and other causes and has pledged to donate at least half of his fortune to charitable organizations.

Oklahoma artist Mike Wimmer, who painted the portrait, says Pickens' name and works will outlive his painting.
