With Warhol's permission, Mr. Ekstract took them to a commercial printer, who made a second set of self-portraits, following Warhol’s directions given over the phone. As part of the deal, one of the portraits would appear in Mr. Ekstract’s new magazine, Tape Recording. To celebrate the magazine’s debut, Mr. Ekstract, with characteristic flair, threw a party on abandoned rail tracks underneath the Waldorf Astoria hotel. Despite ample documentation about its origins, when Mr. Simon-Whelan asked to have the work authenticated by the Warhol Foundation, his request was denied multiple times. He sued, and in 2010, after the foundation had spent $7 million in legal fees, Mr. Simon-Whelan gave up, having run out of money to continue.
