Artist Jeff Koons — whose sculpture “Tulips” sold to Las Vegas casino mogul Steve Wynn for $33 million last year — has designed a $20,000 bottle of bubbly for Dom Pérignon. The collaboration includes a bottle of Dom Rosé Vintage 2003 inside a Koons sculpture modeled on his 2012 work “Balloon Venus.” The limited-edition champagne sculptures — of which only “a few hundred” are being made — come out in September. The Dom Pérignon label has previously made bottles inspired by Andy Warhol and David Lynch. Koons made waves in the spring when he branched out from his longtime gallerist Larry Gagosian to launch a May show with rival David Zwirner.
