In pictures: Freddie Mercury’s beloved piano, song drafts and hundreds of personal items to go on sale

More than 1,400 of Freddie Mercury’s personal items, including his flamboyant stage costumes, handwritten drafts of 'Bohemian Rhapsody' and the baby grand piano he used to compose Queen’s greatest hits, are going on show in a free exhibition at Sotheby’s London ahead of their sale.

The vast collection of the singer’s personal belongings, which had been left to Mercury’s close friend Mary Austin, had remained undisturbed in his west London mansion for 30 years since his death in 1991. Austin, 72, said in a BBC interview in April that she has decided to sell almost all the items to “close this very special chapter in my life” and “put my affairs in order.”

Among the hundreds of Mercury’s personal treasures were his dazzling sequin catsuits, leather jackets and the lavish red cape and crown he wore on his last Queen performance in 1986, as well as previously unseen working drafts of hits 'Don’t Stop Me Now', 'We Are the Champions' and 'Somebody to Love'.

The star of the show, however, is Mercury’s beloved Yamaha baby grand piano, which is set to sell for 2 million to 3 million pounds ($2.5 million to $3.8 million). The piano survived several house moves, took center stage at his mansion, and was the heart of Mercury’s musical and personal story from 1975 until his death, auctioneers said on August 3. “Of all the objects that he had, this is the one that meant the most to him,” said Gabriel Heaton, a specialist at the auction house.

The handwritten draft of 'Bohemian Rhapsody' — which shows that Mercury experimented with naming the song 'Mongolian Rhapsody' before crossing it out — is expected to fetch 800,000 to 1.2 million pounds ($1 million to $1.5 million).

“(Mercury) wrote this: ‘I like to be surrounded by splendid things. I want to lead a Victorian life, surrounded by exquisite clutter,’” said Sotheby’s specialist Thomas Williams.

Other highlights include Mercury’s art collection, featuring works by Pablo Picasso, Salvador Dali and Marc Chagall; handwritten invitations to his birthday bashes and dinner parties — including one dated 1977 that instructed guests to “Dress to Kill!”; and his eclectic collections of antique furniture, Japanese kimonos and cat figurines.

The hundreds of items have turned the auction house’s elegant central London building into a shrine to Mercury, with all 15 of its galleries devoted to his story. It is the first time Sotheby’s is opening its entire gallery space to the public for the weekslong exhibition, Williams said, adding it is perhaps its “most democratic sale,” with items like Mercury’s chopsticks and sewing kit starting at under 100 pounds ($125) each.

The exhibition, which is free to view, opens today and runs until Sept. 5. The items will then be sold in a series of auctions later that month.
