An eBay user called "jaybuysthings" is currently auctioning off the opportunity to discover the true identity of the mysterious British graffiti artist.

"If you win this auction I will mail you a piece of paper revealing the true identity of 'Banksy,'" the item description reads. "I have uncovered his identity by matching up the prices of his sold pieces to corresponding tax records. I will reveal no more details.

"The winner of this auction is the only person I will ever share this information with. The piece of paper will say his name, nothing more.
