John Tunnard (1900–71) is one of that shamefully extensive body of distinguished 20th-century British artists whose work is largely unfamiliar today. For reasons best known to itself, the Tate doesn’t see it as its duty to bring such artists before the public for reassessment, so the job is left to others.
