Hard on the heels of the death of Lucian Freud comes the departure of another British art great, an artist who was Freud’s exact contemporary but who seems to belong in a different aesthetic universe – Richard Hamilton.

His work was too challenging, too difficult to pin down and it never told Britain anything it wanted to hear about itself.
