Formula 1 legend Michael Schumacher has signed a helmeꦍt for Jackie Stewart to help the three-time champion raise money for dementia researc💜h.

Schumacher, w🔯ho hasn’t made a public appearance in over a decade, wrote his initials MSC on Stewart’s helmet with assistance from his wife Corinna.

T♋he Scot has received signatures from all 20 living F1 champions and will wear the signed helmet during a parade lap iꦬn a Tyrrell 006 ahead of Sunday’s Bahrain Grand Prix.

Stewart, who was instrumental in🐼 making F1 safer for drivers in the 1970s, set up a charity Race Against Dementia in 2016 after his wife Helen was diagnosed with the disease.

"It is wonderful that Michael could sign the helmet iꦬn this worthy cause, a disease for which there is no cure," Stewart told the Daily Mail.

"His wife (Corinna) helped him, ✤and it completed the set of every single champion still with us."

Schumacher suffered a severe brain injury while skiing in the𝔉 French Alps in December 2013, just a year after retiring from F1 for the second time.

He continued to undergo reꦆhabilitation at his home in Switzerland, with his family maintaining strict privacy about his con𝔉dition.

The German remains one of the greatest F1 drivers of all time,ꦿ having clinched seven world titles, 9♈1 race victories and 68 pole positions.

While heꦐ won his first two F🧸1 titles with Benetton, he is best known for his incredibly successful stint with Ferrari between 1996-2006.
