A look at the history of Manhattan real estate with Andy Warhol connections suggests that, as in-demand as his Pop Art might be, he doesn't have much pull when it comes to selling property. His 66th Street and Lexington Avenue townhouses had a few close encounters with the Chopper, and the 66th Street place was pulled off the market without selling. But that doesn't stop every vaguely Warhol-related townhouse from enjoying its 15 minutes. Today EV Grieve throws the spotlight on 321 East 6th Street, which, according to the listing, was owned by Warhol in the late 1960s. A half-ownership in the property, which works out to two floors and a landscaped garden with a pond, is available for $2.4 million.
