The museum produced a yellow stamp, saying the artworks on show "may cause shock, vomiting, confusion, panic, euphoria and anxiety." and Ofili's painting was shown behind a Plexiglass screen, guarded by a museum attendant and an armed police officer. Jeffrey Hogrefe, art critic for the "New York Observer", commented about the museum, "They wanted to get some publicity and they got it. I think it was pretty calculated." The editor-in-chief of the New York City "Art & Auction" magazine, Bruce Wolmer,said: "When the row eventually fades the only smile will be on the face of Charles Saatchi, a master self-promoter."
