Nirvana has filed a lawsuit against fashion designer Marc Jacobs over a design featured in the brand's “Redux Grunge” collection. According to TMZ, Nirvana's lawsuit centers on a design featuring a squiggly yellow smiley face, which is very similar to the trademark owned by the band since 1992.

The collection is said to celebrate the cultural significance of the clothing that went on to become a badge of cool in an era presided over by Nirvana and its late frontman, Kurt Cobain. Included in the collection are socks, shirts and sweaters.

The exact origin and meaning of the iconic Nirvana “smiley face” logo with its crossed-out eyes and its drooling mouth are unclear, but most people believe it was drawn by Cobain and made it first appearance on a flyer for the release party for his band's classic Nevermind album in September 1991.

Cobain took his own life at his house in Seattle on April 5th, 1994 at the age of 27. The surviving members of Nirvana, including Foo Fighters leader Dave Grohl, gave a four-song performance at the band's 2014 induction into the Rock and Roll Hall of Fame, with Joan Jett, Sonic Youth's Kim Gordon, Lorde and St. Vincent singing in place of Cobain.

They reunited again at the end of Foo Fighters' set at the Cal Jam festival on October 6th to perform six songs. Grohl, guitarist Pat Smear and bassist Krist Novoselic were joined on vocals by Jett and Deer Tick frontman John McAuley.
