The guitar, a 1959 Martin D-18E, was played during the band’s performance in November 1993, just five months before Cobain’s death at the age of 27.

The guitar is the headline item for the Music Icons event to be hosted by Julien’s Auctions in Beverly Hills in June. 

Darren Julien, president of the auction house, commented: “This important guitar has earned its rightful place in rock‘n’roll history as the instrument played by one of rock’s most influential musicians and icons in one of the greatest and most memorable live performances of all time.”

Cobain’s guitar comes with the original hard-shell case decorated with a flyer from the punk rock band Poison Idea’s 1990 album Feel the Darkness, The Guardian reports.

Three baggage claim ticket stubs are attached to the handle of the guitar case, along with an Alaska Airlines sticker. The storage compartment contains Cobain’s half-used pack of guitar strings, picks and a suede “stash bag”.

Along with the Unplugged guitar, the Music Icons sale will feature other Nirvana memorabilia, including a Fender Strat used by Cobain during the 1994 In Utero tour and the silver lamé shirt he wore in the band’s Heart-Shaped Box video.
