Two of the art world’s smartest salespeople have kissed and made up. Gagosian Gallery marks its re-representation of Damien Hirst with a solo stand (B61) at Frieze New York that features some of the artist’s greatest hits, including a black sheep in formaldehyde (2009). The artist and gallery ended their initial relationship after 17 years in 2012, but Larry Gagosian recently told the New York Times: “Great artists, like great people, have second acts.” Across the way, White Cube (C57) reminds visitors that it also represents Hirst, with one of the artist’s newer pantone works, 12 Colours with Blues (2016).
