The helmet, signed by every living world champion, will raise funds for Sir Jackie Stewart’s Race Against Dementia charity

Formula 1 champion Jackie Stewart wore a helmet bearing the signature of all living Formula 1 champions including Michael Schumacher as he drove one of his title-winning cars for charity at the Bahrain Grand Prix on Sunday.

Michael Schumacher has signed a helmet with the help of his wife 12 years after a ski crash in which he suffered a near fatal brain injury. The seven-time Formula One world champion signed his initials on the helmet with the aid of his wife Corinna. The helmet will be auctioned to raise money for Stewart’s Race Against Dementia charity.
