London, August 21 : A nude picture of former US First Lady Jackie Kennedy Onassis has been discovered in the pile of King of Pop Art Andy Warhol''s possessions.

The snap, which apparently shows the wife of John F. Kennedy skinny-dipping, was said to have been signed "For Andy, with enduring affection, Jackie Montauk", a reference to the painter’s beach front estate in Montauk.

Archivists sieving through 610 cardboard boxes, filing cabinets and a shipping container belonging to Warhol, who is considered a leading figure in the visual art movement known as pop art, found the photograph, reports the Telegraph.

Researchers working for the Andy Warhol Foundation also found a piece of crusty wedding cake and 17,000 dollars in cash amongst other items.

Matt Wrbican, who has been going through the artist''s things since 1991, said: "He really didn''t like organisation and there would be several boxes going at a time.”

He added: "The only rooms that looked like a normal house were the bathroom and the kitchen.” (ANI)
