Tim Henman is used to drawing a crowd at Wimbledon but for once the crowd gets to draw him.
A large canvas will be put up outside the courts and queuing fans will be able to colour in a drawing of him playing tennis legend Fred Perry.
The outline was created by Christian Furr who will be on hand on Tuesday and Wednesday to offer painting advice.
The British number one said: "I love the idea that I'll be able to see myself playing one of my heroes."
Colour and sepia
Mr Furr said: "The queue will be given sections of the canvas to work on, so it will gradually come together throughout the day - we're hoping some of the tennis players will come down and paint along side their queuing fans."
He spent more than 150 hours drawing the outline of the picture after Henman spent a day sitting for him in his studios.
Mr Furr sketched Henman's opponent Fred Perry, after studying photographs of the last British player to win Wimbledon in 1936.
Henman's side of the court will be in colour and Perry's side is in sepia tones.
The painting was commissioned by Robinsons drinks to mark their 70 years on Centre Court.
