A unique helmet worn by Formula 1 legend-in-the-making Sebastian Vettel will be auctioned off at Bonhams Goodwood Festival of Speed sale on June 27.

Vettel wore the Arai headgear, created by Jens Munser Designs, at the Monaco Grand Prix in 2013, where he drove for Red Bull.

The image on the crown commemorates Sir Stirling Moss’s famous 1961 victory in Monaco, and the back of the helmet features a vintage-style Pepe Jeans pinup whose clothes become more transparent as the helmet heats up.

Which it’s expected to do to the tune of about $17,000 this weekend…
