Dan Gurney pioneered the use of Bell's full-face helmet in F1 in 1968, but six years earlier, back in 1962, the great American driver was already searching for ways to improve his protection.

In this shot taken at the 1962 US Grand Prix at Watkins Glen, Gurney is seen chatting to Porsche team mate Jo Bonnier and wearing a leather mask, which resulted in a bit of a 'Darth Vader' scary look.

The concept was quickly ditched however because of its lack of comfort.
