According to TMZ, NIRVANA has filed a lawsuit against Marc Jacobs over a design featured in the brand's "Redux Grunge" collection. The collection celebrates the cultural significance of the clothing that went on to become a badge of cool in a cultural era presided over by Kurt Cobain. Included in the collection are socks, shirts and sweaters.

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 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 "Nevermind" album in September 1991.

Kurt Cobain took his own life at his house in Seattle on April 5, 1994 at the age of 27.

The 20th anniversary of his death led to a resurgence of interest in its circumstances, which was heightened by the release of never-before-seen photos from the scene.

The anniversary fell just a few days before NIRVANA was inducted into the Rock And Roll Hall Of Fame. The surviving members of the band gave a four-song performance at the ceremony, with Joan Jett, SONIC YOUTH's Kim Gordon, Lorde and St. Vincent singing in place of Cobain.
