An extremely rare ball, this is very difficult to find signed or unsigned, let alone mint in box. It's an Official baseball with six teams on original label: Grand Rapids, Battle Creek, Rockford, Kalamazoo, South Bend and Fort Wayne. Best of all, the ball is oversized at 10" in diameter. DeBeers Double Header ball with the stamp of the league President Harold Van Evans Jr. The box is in EX condition, and the ball is perfect.
