Over 8,000 entered the competition, and now Mercedes have unveiled the winning design via their Twitter page.
The Brit will use the winner’s design throughout the 2017 season and the winner will also receive a full-sized replica that has been signed by the three-time World Champion.
Hamilton has announced that Raí Caldato from Brazil is the winner.
He wrote on Instagram: “Raí evolves my layout by adding new stripe elements on the sides.
“As a tribute to my hero, Ayrton Senna the helmet features the colours of Brazil – green, yellow and blue. These are accompanied with the 3 stars that represent my Championship wins.
“There’s yellow throughout that reminds me of my helmets in the past. The candy apple red balances with the yellow very well.
“Raí, I look forward to meeting you in person to present you with your prize! Thank you all for entering this competition, I’m taken back by your creativity.
