Upon receiving the franchise, Oakland civic leaders found a number of businesspeople willing to invest in the new team. A limited partnership was formed to own the team headed by managing general partner Y. Charles (Chet) Soda, a local real estate developer, and included general partners Ed McGah, Robert Osborne, F. Wayne Valley, restaurateur Harvey Binns, Don Blessing, and contractor Charles Harney[7] as well as numerous limited partners. A "name the team" contest was held by a local newspaper, and the winner was the Oakland Señors. After a few weeks of being the butt of local jokes the fledgling team (and its owners) changed the team's name to the Oakland Raiders, which had finished third in the naming contest.[8] The original team colors were black, gold and white. The now-familiar team emblem of a pirate (or "raider") wearing a football helmet was created, reportedly a rendition of actor Randolph Scott.[
