Mika Häkkinen, the renowned Flying Finn, was on the verge of returning to Formula One for the 2007 season, five years after his retirement. In his final F1 testing session with the McLaren MP4-21, which took place in Barcelona in November 2006, Häkkinen utilized this authentic Bell HP3 race helmet. This helmet, bearing the 2007/01 tag on its back, has been diligently matched with photos and comes with a certificate of authenticity (COA) from McLaren.
