Eminem has launched a T-shirt line to raise money for the children of D12's Proof, the Detroit rapper who was shot and killed at a nightclub on the city's famed 8 Mile strip in April.

Deshaun "Proof" Holton, whom Eminem called his best friend at the memorial service, was a father of five. The T-shirts and a poster, which are being sold at BigProof4Ever.com, feature an iconic image of the late rapper created by the noted graphic designer Shepard Fairey.
