DETROIT —  A little bit of Eight Mile Road history signed by Eminem (search) is on its way to Nebraska.

Someone from the Cornhusker State paid $685 for the last of 30 commemorative bricks from the recently demolished Detroit Artillery Armory on Eight Mile in Oak Park. That's the most paid for any brick during the nearly three-month auction on the Internet auction site eBay, the Detroit Free Press reported Wednesday.

Eminem, who grew up on both sides of the roadway and made it famous in a hit song and film, autographed the commemorative bricks. They were sold as a fund-raiser for the 32-year-old rapper's charity, the Marshall Mathers Foundation, which helps troubled youths, and the Eight Mile Boulevard Association.

Tami Salisbury, the association's executive director, said the project raised more than $8,500.

The association asked Eminem, whose real name is Marshall Mathers III (search), to sign the bricks. It plans to use its share of the auction proceeds for revitalization efforts.
