I have only just got round to studying the annual charts of visitor numbers which are inserted into the April issue of the Art Newspaper. The National Palace Museum in Taipei takes the top eight places. Chanel at the Saatchi Gallery came twelfth in the world, way above the wonderful Alexander McQueen exhibition at the V&A. I initially thought that Ai Weiwei came top amongst UK exhibitions, but then spotted that it had been beaten by six exhibitions at the Saatchi Gallery, including Skate Girls of Kabul. I’m also pleased to see the Summer Exhibition up there in the top fifty in the world with 230,483 visitors. William Kentridge did well in Beijing, but so, I thought, did Sean Scully at the Himalyas Museum in Shanghai. Maybe they don’t supply the statistics. The National Portrait Gallery got over 2 million visitors, nearly double Tate Britain. Nearly 200,000 people went to see Grayson Perry in Margate. Some people think museum directors are obsessed with visitor numbers. I am.
