It's wonderful! Michael Schumacher signs helmet for charity auction. PHOTO

The legendary racing driver Michael Schumacher put his signature on a special helmet for Jackie Stewart's charity organization "Race Against Dementia".

According to the Daily Mail, the "Red Baron's" signature was assisted by his wife Corinna. As seen in the photo, the initials of the German racer M.S. are inscribed on the helmet.

"It is wonderful that Michael could sign the helmet in this worthy cause – a disease for which there is no cure. His wife helped him, and it completed the set of every single champion still with us," Stewart told The Mail journalists.

The helmet will be showcased before the main race at the Bahrain Grand Prix, Formula 1.

Recall that Michael Schumacher has not appeared in public since 2013, following a severe brain injury sustained while skiing. Since then, the racer's family has limited visitors who can see him and has kept details of the German's current condition private.

It was previously reported that Michael Schumacher became a grandfather: his daughter gave birth to a girl.
