Hardwell is auctioning a limited edition copy of his 2YearsAsOne book for UNICEF.
The hardback book – that will be signed by Hardwell – documents the two years he spent as The World's No.1 DJ.
This prize has extra poignancy, following Hardwell's recent decision to take an indefinite hiatus from touring and the music industry.
This collectors item is open for bids now and will go to the highest bidder. All proceeds support the work of UNICEF.
The auction runs until Wednesday 17th October 2018 at 19:30 (BST).
