The Royal College of Art in London has long been one of the leading art education establishments in the world and so its collection of works donated by former pupils and teachers, that was begun by the painter Sir William Rothenstein when he was appointed rector in 1920, inevitably includes many greats. Works by such pillars of the art world as Tracey Emin, David Hockney and Peter Blake are included, as well as, pieces by earlier artists like Kitaj and Barbara Hepworth.
