"The Duke" is the name of the NFL football. Wilson has produced it since 1941 and is the longest collaboration in the history of American sports.
The ball is produced by hand at Wilson's factory in Ada, Ohio, at a rate of up to 2,500 units per day. The retail prices of the balls range between $45 and $249 for a special edition made on the occasion of the grand final in Las Vegas. The Kansas City Chiefs and the San Francisco 49ers will meet on Sunday in the 58th edition of the Super Bowl.
