Giant Lewis Hamilton portrait in Potters Fields Park

A tiny crowd braved the rain for the unveiling ceremony on Thursday lunchtime to see artist Ian Cook unveil his latest work in Potters Fields Park.

The Birmingham-based artist has spent the week using remote-controlled model cars to cover the 8 metre by 12 metre canvas.

A recorded message from Lewis Hamilton in Brazil was played on a big screen at the unveiling ceremony.

"I want to send major props to Ian Cook for the job he's done," said the 23-year-old driver.

"I've just seen the video and how you constructed the painting ... you've really captured my face and the whole shape of my body. It's mindblowing."

The picture, commissioned by Reebok, will remain in Potters Fields Park until Sunday.
