Commissioned by Trespass outerwear, the fifteen pieces feature everything from a hand-painted glazed doughnut covered in sprinkles to a spectacular plastic-moulded skull, a wily bright pink octopus and an intricate tattoo-inspired design.

Stephen Wiltshire MBE, the world famous artist who suffers from autism and draws completely from memory, has contributed a stunning London cityscape, scrawled meticulously onto the helmet in pen.

He said, "I have used a guitar, balloon and travel luggage as a canvas for my art before, but never on a snowboard helmet, so taking part in the Snowcase project was a fresh and enjoyable challenge.

"I decided to draw my favourite London landmarks from Royal Albert Hall to the Shard and add my motto 'Do the best you can and never stop' so my work might inspire people."

Stephen's artwork helmet will help raise funds for Barnardos. Other charities to benefit from the Snowcase project include: Prostate Cancer UK, Doctors Without Borders and Alzheimer's Research UK.

Stephen added: "I like to help in any way I can and representing Barnardo's for this auction is a really worthwhile way to help the charity, which provides much needed support for young people."

Morag McIntyre, Partnerships Development Manager for Barnardo’s, said: “Barnardo’s is delighted to be a beneficiary of the innovative 2016 “Snowcase” campaign, as we recognise 150 years of support for vulnerable children and young people. 

"The money raised through Trespass charity auction and the contributing artists will help Barnardo’s give children who are in desperate need someone to turn to. On behalf of these children, thank you.”

The other artists involved in the project include illustrator and cartoonist Joe Berger, painter and experienced graphic designer Dairo Vargas and world-renowned artist Louise Dear. To find out more and to bid for one of the unique art works please visit: http://www.trespass.com/snowcase
