Warhol copied a portrait. Totally different issue.
"The supreme court [lol @ Anti-American Grauniad] focused on the specific use that allegedly infringed Goldsmith’s copyright – a license of Warhol’s work to Condé Nast – and said it was not transformative because it served the same commercial purpose as Goldsmith’s photo: to depict Prince in a magazine."
