In 2001, Louise Bourgeois’s “Maman,” a 30-foot-tall spider accompanied by two smaller arachnids, welcomed (or perhaps scared away) people at Rockefeller Center. The year before, a 42-foot sculpture of a dog, called “Puppy,” towered over Rockefeller Center. It was covered in 70,000 flowering plants. Last year, another similar, oversized Jeff Koons structure called “Split-Rocker” came to Rockefeller Center, which was half pony and half dinosaur. Rockefeller Center has been home to several oversized art installations over the years.
