A painting of John F. Kennedy Jr. by Cork-born artist Patrick Hennessy has risen in value to almost $100,000, after it was bought for $600 at an auction in 2003, the Irish Times reports. It’s for sale at a gallery in New Orleans.

The image depicts the U.S. president boarding air force one at Shannon in 1963. That would be the last time he would set foot in Ireland. He was assassinated later that year.

Time reporter Michael Parsons writes: “In 2003, the painting appeared at a small rural auction in the United States and was spotted by a collector in Dublin who bought it for $600. He brought it back to Ireland and, a year later, consigned it to auction at Whyte’s in Molesworth Street who estimated its value at €8,000-€10,000.”

The painting is believed to have been returned to the U.S. by a London dealer, who purchased the painting for $20,000 in 2004.
