New York's spring auction week, starting May 18, 2026, saw record-breaking sales led by Christie's, which realized over $1.1 billion across two opening night sales. Major estate consignments from Condé Nast owner S.I. Newhouse, MoMA trustee Agnes Gund, dealer Marian Goodman, and financier Robert Mnuchin fueled the market, resulting in 17 new artist auction records.
Banksy's painting *Girl and Balloon on Found Landscape* sold for $18 million (£13.3 million) at a Fair Warning auction held at Tiffany & Co.'s Landmark store in New York. The 2012 work, which reimagines a traditional pastoral landscape with the artist's iconic balloon motif, was purchased by an anonymous US bidder after a phone battle. The result places it among the three highest auction prices ever achieved for a Banksy artwork, surpassing *Sunflowers From Petrol Station* and trailing only *Game Changer* and *Love Is in the Bin*.
