On December 8, 1980, RKO Radio host Ron Hummel interviewed John Lennon and Yoko Ono at their apartment in the Dakota Building about the couple’s recently released record Double Fantasy. At the end of the interview, Hummel asked for an autograph and Lennon obliged, scrawling his name in black felt-tipped pen across a large-format promotional poster for the album. By the end of the day, Lennon would be shot dead.

That poster, marked with what is understood to be one of the musician’s last autographs, is heading for auction in the U.K. at the end of the month where it has been given an estimate of £60,000 to £120,000 ($79,200 to $158,400). At Propstore’s Music Live Auction in London on April 30, the poster—which uses Kishin Shinoyama’s photograph of Lennon and Ono kissing in Central Park—will be accompanied by RKO’s archives from that afternoon, including CDs containing Lennon’s final interview.

“It’s an incredible piece of unique music history,” Propstore’s music specialist Mark Hochman said over email. “It would become the centrepiece for any serious collector or fan.”

This slightly morbid piece of memorabilia is one of more than 400 items set to hit the block that capture some of music history’s most iconic characters.

The lead lot is the flame-patterned Gibson Les Paul guitar that Slash played throughout Guns N’ Roses’s 2016 tour Not In This Lifetime. The 175-show tour was the first time that Axl Rose, Duff McKagan, and Slash had played together since the early 1990s and went on to generate more than $500 million. The instrument, which Slash has called “really the best all-around guitar for me,” has been given an estimate of £150,000 to £300,000 ($198,000 to $396,000).

The British band Queen is heavily represented on account of a consignment of more than 60 items from Peter Hince, the band’s head roadie for 11 years. Here, the marquee offering is a Shure 565 SD golden microphone that was presented to frontman Freddie Mercury in 1980 by Circus Magazine. It was gifted to Hince as a thank you from Mercury and is estimated at £30,000 to £60,000 ($39,000 to $79,000).

Hince—whose photographs form the basis of the exhibition “Queen Unseen,” recently on view at Italy’s Palazzo Guinigi—also consigned Mercury’s beige dressing gown, estimated at £10,000 to £20,000 ($13,300 to $26,600), and a Christmas card he received from the singer in 1987, which is estimated at £3,000 to £6,000 ($3,900 to $7,900).

Inevitably, Beatles-affiliated memorabilia is peppered throughout the sale. Aside from the Lennon autograph, there is a first-draft of Paul McCartney’s lyrics for the song “Goodbye” in 1969. Although the Beatles would record a demo, the song was eventually performed by Mary Hopkin and would reach No. 2 in the British charts. The page of lyrics, which are written on Apple Records official letterhead, has an estimate of £55,000 to £110,000 ($73,100 to $146,000). A running order sheet, signed by all four Beatles, from the band’s second appearance on The Ed Sullivan Show in 1964 has been given an estimate of £30,000 – £60,000 ($39,000 to $79,000).

“Featuring stage-used instruments, handwritten lyrics and iconic performance-worn pieces, the sale spans genres, generations and defining cultural moments,”Hochman said in a statement. “Each lot offers collectors a tangible connection to the artists and performances that helped shape the soundtrack of our lives.”
