1988-9 Ayrton Senna signed replica helmet.
This is a perfect copy of the Bell helmet that Ayrton wore in both 1988 (McLaren MP4-4 Honda WC) and 1989 (McLaren MP4-5). It has been clearly signed and dated on the visor by Ayrton in 1989. This is the correct SA85 Snell rated size 7-3/8”/ 59cm Bell XFM-1 helmet.
It is expensive but still much less than an original! (k02C)
This of course comes with our lifetime certificate.
