Dwayne Walker said in a lawsuit filed in Manhattan federal court on Thursday that he created the Roc-A-Fella design.
The lawsuit says the Bronx designer came up with the logo in 1995 when Roc-A-Fella was just starting out. The label is now a subsidiary of Universal Music Group.
The logo features the letter R, a record and a Champagne bottle.
