Celebrities such as Brian May, Beyoncé, Noel Gallagher and Sir Cliff Richard have donated items to be auctioned off for the Teenage Cancer Trust.
Queen guitarist Brian May has donated a signed amplifier for the auction, alongside a bag handed over and signed by Beyoncé and the rest of Destiny's Child.
Line Of Duty star Vicky McClure has donated a dress, while The Who, whose singer Roger Daltrey is a long-time supporter of the charity, have donated a signed tin of baked beans.
Also among the items are Gallagher's limited edition Stan Smith Adidas trainers and a shirt donated by Sir Cliff.
McClure said: "I am such a proud ambassador of Teenage Cancer Trust that when I heard about the Star Boot Sale, I was more than happy to donate.
"The dress I have given is the only one Kate Fleming has ever worn in Line Of Duty, when she was presented with an award at the end of series three, so it's a real part of the show's heritage."

She added: "Teenage Cancer Trust nurses and youth teams are absolute heroes and have been working tirelessly throughout the pandemic to support young people with cancer.
"But everything the charity does is reliant on being able to raise money, so get on to the auction and get bidding so they can keep doing great work."
Daltrey said: "Young people with cancer are particularly at risk from coronavirus.
"And right now, Teenage Cancer Trust-funded nurses and support teams are going above and beyond to provide the care they need at a time when healthcare services are under huge pressure.
"They are amazing people – but not many people realise that their work is completely reliant on fundraised income and donations.
"So please get involved in this new fundraiser if you can.
"Our friends from across the entertainment industry have searched their cupboards and donated some great stuff and remember every penny raised will make a difference."
All the items can viewed online, with the auction and raffle running from Friday to 6 May at 8pm.
