Jeff Koons is headed back to Rockefeller Center with Seated Ballerina, a new public art project co-presented by the Art Production Fund and Kiehl’s Since 1851. Perhaps best known for his Balloon Dog, a shiny, stainless steel sculpture that looks like a Mylar balloon—an orange version holds his personal auction record for a $58.4 million 2013 sale at Christie’s New York—Koons is making only his second ever inflatable public artwork for the occasion.
