Sorry, fans of Warhol, and anyone who was trying to make bank off a flashy new museum coming to a gentrifying neighborhood. Nearly two years after announcing its plans to erect an outpost at Essex Crossing, the massive development that's set to take over a few vacant lots at Seward Park on the Lower East Side, Warhol Museum director Eric Shiner said the plans have been abruptly canceled. He was pretty vague about why plans for a 10,000-square-foot institution just disappeared.
