NEW YORK (AP) - October 30, 2009
The painting belongs to Cathy Naso. She was 17 years old when she got a part-time job as a receptionist at Warhol's Factory.
Two years later, in 1967, Warhol gave her a self-portrait inscribed to her.
The Brooklyn resident displayed the painting briefly and then stored it in a closet. It remained there until this year.
It is on display at Sotheby's New York offices starting Friday and will be auctioned at a Nov. 11 sale of contemporary art.
The auction house estimates it will sell for $1 million or more.
