Around 1,500 personal possessions of Freddie Mercury, the renowned British singer and lead vocalist of the band Queen, are currently being auctioned off by his close friend, Mary Austin. Austin inherited these possessions from Mercury, who left her half of his estate, which is valued at 75 million euros, along with a Georgian mansion in Kensington.

Austin had been considering this idea as a way to begin a new chapter in her life. She expressed, “For many years now, I have had the joy and privilege of living surrounded by all the wonderful things that Mercury sought out and so loved. But the years have passed, and the time has come for me to take the difficult decision to close this very special chapter in my life.”

Some items are up for sale, including the iconic comb that has the late British rock star’s “never-before-seen” handwritten draft lyrics for the legendary song “We Are the Champions” on it. Along with that, the pink star-shaped glasses similar to those worn by Mercury in the music video for “We Will Rock You” and his stylish mustache comb from Tiffany & Co. Also up for auction is Mercury’s guitar, which is believed to have been used to write and record the song “Crazy Little Thing Called Love.” The sale includes the waistcoat worn by Mercury in his final music video, “These Are the Days of Our Lives,” in 1991, alongside a Pablo Picasso linocut entitled “Jacqueline au chapeau noir.”

Lastly, the crown and cloak worn by Mercury during his performance of “God Save The Queen” on his last tour in 1986 are expected to fetch up to 80,000 euros or $100,000 U.S. dollars. This crown is thought to have been loosely modeled after the crown King Charles III wore at his coronation on May 6th.

Sotheby’s, a marketplace of art and luxury, announced an exhibition from August 4th to September 5th showcasing items from the life of the legendary musician. The exhibition will feature immersive galleries dedicated to different aspects of his life. A limited-edition collection book will be released alongside the auction.

A portion of the proceeds from the sale will be donated to the Mercury Phoenix Trust and the Elton John AIDS Foundation in honor of Freddie’s memory. Highlights from the collection will also be touring in New York, London, Los Angeles, and Hong Kong throughout the month of June. According to Austin, “It was important to me to do this in a way that I felt Freddie would have loved, and there was nothing he loved more than an auction. Freddie was an incredible and intelligent collector who showed us that there is beauty, fun, and conversation to be found in everything; I hope this will be an opportunity to share all the many facets of Freddie, both public and private, and for the world to understand more about, and celebrate, his unique and beautiful spirit.”
