With vibrant brushstrokes of color and found objects, artist Christopher Obetz’s Pop Art Golf series presents a fresh take on the sport.Nearly two decades ago, multimedia artist Christopher Obetz hit the jackpot when he stopped inside a New York City gallery on a walk with his dog. In its back room, behind the exhibition of impressionist and Renaissance paintings, he found thousands of works by the late illustrator Anthony Ravielli, whose acclaimed depictions of golfers in motion graced the pages of the sport’s most celebrated guides. “I thought, ‘My God, this is like the holy grail of golf instruction,’” the Fort Myers-based artist says.
