Vincent Van Gogh: Newly discovered drawing goes on display

“The artist began by drawing a grid on the paper, which tells us that he worked with a perspective frame to help him capture a figure quickly with the correct proportions. He then worked the sheet up in his characteristically expressive drawing style: not refined, but with energetic scratches and strokes and laying down contours, in search of a pithy image with special attention to effects of light and shade.’
