All funds raised from the auction will go to Children's Heart Surgery Fund.
Supporters can now get their hands on a pair of football boots from Leeds United player Jack Clarke, which have been made available for auction.
The boots have also been signed by the winger who is currently on loan from Premier League club Tottenham Hotspur.
All of the proceeds generated from the auction will go straight to Children's Heart Surgery Fund, the charity partner for the club during the 2018/19 season.
The funds raised will be used to help purchase life-saving equipment for the Paediatric Intensive Care Unit at Leeds Children's Hospital.
