Tony Riff's Attitude, which won our competition based on a brief from Subism, can now be purchased. Also check out a video of Waste screenprinting it.

Tony -- aka Anthony Sekyere -- created his print in response to a brief set by Stuart Boyd of Subism as part of our feature where leading creatives from Jon Burgerman and Erik Spiekermann to Rian Hughes and Mary Lizzie Cullen set projects for you to try.

Here's Anthony's winning piece. It's a brilliant artwork that will look stunning on the wall of a creative studio or home. We were also really struck by the subtle use of colour - which draws in the blues and red of anaglyphic 3D. And yeah, we're still not over our owl obsession either...

Here was Stuart's brief:

"When David Cameron made his first official trip to Washington, one of his official gifts for President Obama was UK artist Ben Eine’s piece, Twenty First Century City

"I challenge you to create a three-colour artwork fit for a king -- or president, prime minister or other head of state -- and enter it into an exclusive competition to see it released as a limited-edition screenprint by Waste (wasteyourself.com). Each print of your work will be sold on the Subism online store for a £50."

Subism has also posted a video of top screenprinter Waste creating the pieces.
