Stan's charity shop '˜n' sketch at The Mall, Luton

Portrait arist Stan Hurr who will be at The Mall in Luton from February 23

Part of his profits go to The Mall Cares initiative and he has raised more than £5,000 since his first visit to the centre in 2011.

Stan – who’s been a professional artist since 1980 – says he loves coming to the Luton mecca: “It’s such an interesting place to work as there’s such a diverse mix of people.

“And with the airport just around the corner, you feel like you’re taking a trip around the world – it has a real cosmoplitan feel.” He added: “It’s so different from sitting on my own at home, working from photographs. I much prefer sketching people live in front of me.”

He offers both black and white and colour portraits as well as caricatures with prices starting from £10, from which 15 percent goes to The Mall Cares. Mall marketing manager Lavinia Douglas said: “Stan is a real hit with our shoppers.”
