Back in the early 1990s, truck driver Teri Horton purchased a drip painting for $5. Now, she wants to sell it: for $20 million. “This is the estimated value of what one forensic art expert has pronounced a Jackson Pollock. However, the prestigious International Foundation for Art Research does not think it genuine… Ms Horton, who is 70 and lives in Costa Mesa, southern California, thinks it is ugly. She kept it only because it would not fit through the front door of the friend for whom she bought it from a thrift shop.”
