British art collectors have been urged to engage in more charitable giving after a multi-million pound painting donated by an American tycoon and his wife was unveiled at the Tate Modern.
A six-metre-long triptych, valued between £2.2 and £3.7m, by the celebrated abstract expressionist Joan Mitchell was gifted to the gallery by Miami businessman Jorge M Pérez. It is on free display opposite Mark Rothko’s Seagram Murals from Thursday, 3 April.
