Eminem, who grew up on both sides of Eight Mile Road, is helping revitalize the highway he made famous in a hit song and film.
The rapper, born Marshall Mathers the Third, has autographed 30 bricks from the recently demolished Detroit Artillery Armory on Eight Mile in Oak Park.
One brick was auctioned last month, and the rest are to auctioned on eBay within the next month.
Proceeds will be split equally between the Marshall Mathers Foundation and the Eight Mile Boulevard Association.
The association plans to use its share of the auction proceeds for revitalization efforts along Eight Mile.
