At Art Greenwich, David and Lee Ann Lester, owners of International Fine Arts Expositions, usher antique and contemporary art, design, and jewelry from more than 60 international exhibitors into a 228-foot docked megayacht. Fine-arts dealer David Brooker entrances art lovers with masterful works from England and America spanning three centuries. Pieces by Andy Warhol call out to pop-art aficionados, while Green River Stone’s fossilized, fish encrusted murals provide pristine snapshots of what life was like 50 million years ago and what salmon looks like when served at Medusa’s dinner parties. Guests swoon over floral accessories from Yvel and ogle the exquisite works of Murano glass from Mark Helliar 20th Century Design that inspire thoughts of flowers with their intricate, natural design and flower-themed costume parties.

Art Greenwich’s exhibitions are situated aboard the world's first mobile megayacht venue, though the vessel maintains port during the expo to avoid being intercepted by rogue art festivals. The ship, designed by the acclaimed Luiz De Basto, affords guests magnificent views of the harbor as they navigate luxurious parlors and showrooms
