A reward of $25,000 has been offered for information leading to the whereabouts of a ship spinnaker designed by the late Pop artist Roy Lichtenstein. The vessel sailed in the 1995 America’s Cup in San Diego, California; its hull, which is decorated with Lichtenstein’s mermaid motif, features in a show opening this month at Middlebury College Museum of Art in Vermont (Young America: Roy Lichtenstein and the America's Cup; 26 May-13 August). Anyone with information on the missing sail should contact Kevin Mahaney, the ship’s skipper in 1995 who spearheaded the exhibition.
