The signage outside Dulwich Picture Gallery advertising the exhibition of British Surrealism has been very appropriate during the lockdown crisis - the sub-title: ’Season of The Unexpected’, seemed to admirably suit the mood of the times. Accompanying the signage was an example from the show - Conroy Maddox’s The Lesson. This was also a spectacularly appropriate choice, especially with added captions (with apologies to Conroy Maddox and The Lesson)
