IT would seem that nowhere is safe from the Harry Potter mania gripping the nation. Now farmer Tom Pearcy has carefully cut two portraits of the boy wizard into the Elvington maize maze in the hope of creating the world’s largest spot-the-difference competition.

The Guinness Book of Records has been invited to see the tribute to Harry Potter – which, with each head measuring over 50m in diameter, is also believed to be the largest image of actor Daniel Radcliffe ever created.

Mr Pearcy said: “I’m a big fan of Harry Potter and the release of the final film this summer marks the end of an era. I wanted to do something imaginative to say farewell to Harry, so creating the biggest image of him ever made and making it a spot the difference competition seemed like an interesting way to do that.”

The images have been painstakingly carved out of more than one million maize plants.

There are 10km of pathways at the maze, which form intricate routes for visitors to explore.

Mr Pearcy’s previous designs include a Spitfire, an astronaut, the Statue of Liberty and the Flying Scotsman. York Maze opens to visitors this Saturday and will be open every day until September 4.
