Pitt and actors Ben Affleck, as well as Laurence Fishburne, have each donated a motorcycle which will be sold to raise money to erect a monument in Washington in honour of Martin Luther King Jr.
The organizer of this event, Morgan Freeman, explained, "He’s remembered as our prince of peace, of civil rights. We owe him something major that will keep him and his memory alive."
In total four motorcycles will be sold, two belonging to Ben Affleck, and one from Brad Pitt and Laurence Fishburne .
The auction will begin Friday on the site charityfolks.com.
In addition to these items, buyers have the chance to bet their hands on Jennifer Lopez’s shoes, and the DVD Catch Me if You Can, autographed by Tom Hanks.
The monument is expected to be put up in 2008.
