25-panel World Cup Ball 1966 Challenge 4-star from a British company "Slazenger" was produced for the 1966 World Cup in two variants - yellow and orange. This manufacturer has since changed the direction of production, and now specializes in the manufacture of equipment for cricket, tennis and hockey. "Slazenger" balls were sewn by hand. This shell, as before, was chosen blindly FIFA representatives at the headquarters of the FA in Soho. In official matches on the ball there was no branding.
