As Steve Eyre of World of Superheroes in Sheffield, England, was walking through an art exhibition in his hometown last week, he noticed something unusual on the leg of one of the sculptures: The cover to 1963's Avengers #1. That comic was one of dozens of rare, classic comics artist Andrew Vickers used to create his papier-mache work. Vickers had no idea.

All in all, the comics used to make the statue would be worth upwards of £20,000, Eyre estimated. That would be about $30,000 USD.

According to the BBC, Eyre said, "It would have been cheaper for Andrew to make this out of Italian marble because the raw materials that have gone in to it I could have sold for a lot more than he is going to sell this statue for."

Vickers took it all in stride, though.

"To be honest I'm shocked but money has not got such a value to me," he said. "I really love the idea of me creating something out of such expensive things that's worth less. I think it's brilliant."
