In late 2009, I started thinking about the idea of an "invisible" show. Almost two years later, "Seen/Unseen," a 20,000-square-foot exhibition of my work from the preceding six years, opened in an undisclosed industrial space in New York City. Despite the fact that "Seen/Unseen" was closed to the public, a press release was issued via e-flux, a full-page ad was placed in Artforum and announcements about the show were mailed. The exhibition closed on October 28, 2011, four-and-a-half weeks after it opened. This book documents and presents insight into "Seen/Unseen."
