Dwayne Walker a New York City designer says Jay-Z and his former Roc-A-Fella record label partners owe him $7 million in unpaid royalties for designing their label logo. Dwayne Walker said in a lawsuit filed in Manhattan federal court on Thursday that he created the Roc-A-Fella design. Walker claims he created the logo in 1995 when Roc-A-Fella was just starting out and he wants to be compensated.
