Kurt Cobain's vintage, olive-green cardigan sold for a record-breaking amount during a two-day music auction in Oct 2019. The Nirvana singer's cardigan, which he wore at the band's famous "MTV Unplugged" performance in New York in 1993 has sentimental value for a lot of fans. The "Unplugged" concert is considered one of the band's best performances, and it made the thrift-store cardigan iconic.
