Drawing in art galleries can be filed under ‘Why didn’t I think of this before?’ It’s warm, it’s dry and you get to copy other people’s work without anyone complaining. Genius. And the beauty is that you can spend 10- 15 minutes in front of something that is actually genius. All hail to E.R. Hughes, Dante Gabriel Rossetti , Grayson Perry and David Hockney.
