Levi McDaniel, 23, posted an auction on eBay saying he will tattoo the winner's chosen company logo or advertisement on his back -- where it will be seen by his more than 22,000 Twitter followers and the large groups of fans at his wresting matches -- the Des Moines (Iowa) Register reported Thursday.
McDaniel said the idea was suggested by Rock 'n' Roll Wrestling founder Buck Zumhofe.
"A tattoo is a pretty big deal; it's on your body for life," McDaniel said. "We're always in front of people. I would think this is a pretty good investment if I was a company. It would be seen by so many people."
McDaniel said he wants to give 75 percent of the proceeds from the auction to the immediate family of his aunt, who died this week from cancer.
He said the rest would go to a charity, possibly the American Cancer Society.
"If this works, I would like to do the next one with the money going toward the Wounded Warrior Project or some other group that supports veterans," McDaniel said.
The auction, which ends Saturday, had yet to attract any bidders Thursday.
