One hundred years ago, a man in Austria allowed a young painter to create a portrait of his son. Last month, that same painting, now likely valued in the seven figures, was Exhibit A in a legal battle that played out at the Fifth Circuit Court of Appeals in New Orleans. This is the story, as told by the painting’s owner, researched by lawyers arguing the case and affirmed by the court’s ruling, of the canvas’s remarkable journey through history — and the America legal system. The tale begins in 1910, when 24-year-old expressionist painter Oskar Kokoschka visited the home of Viennese art collector Dr. Reichel. The artist asked permission to paint the doctor’s son Hans who was ill at the time. Something about the boy’s stricken state inspired the artist, who was known for his sometime dour, emotion-packed paintings.
