Tate Britain is inviting visitors to write their own labels for art in the galleries. “The 30 most vivid contributions will go up on the walls, beside the efforts of the curators, in time for British Art Week, starting on September 20. More will be added, and may remain for as long as the paintings stay on display. This is the first time the gallery has invited members of the public to join a contentious debate about how to label art.”
