In the early 1990's there simply wasn't a bigger band on Earth than Nirvana. Hailing from the shores of Seattle, Nirvana would take the music World by storm following the release of their 1991 LP Nevermind. Most notable for their Grunge sound forged by the late great Kurt Cobain, Nirvana would change the landscape of Rock music over the course of only a few years. For many reasons Nirvana group signed items are amongst the toughest in all of the hobby, but most notably would be the introverted nature of Cobain that made autograph request nearly impossible. Cobain's final work would be the highly anticipated "In Utero" in late September of 1993; the record quickly made its way to the top of the Billboard charts and has since sold 15 million albums worldwide. Reluctant to accept the fame, Cobain would find himself in a spiral due to his heroin addiction which amassed to Cobain taking his life on April 8th, 1994, just months following "In Utero's" release. Due to the incredibly fame, drug use & personal problems, any item signed post 1991 by Nirvana, let alone just Cobain, are considered an ultimate rarity in the hobby and steadily rising in value. Offered here is possibly the finest piece of Nirvana memorabilia to ever be auctioned, including all four members who contributed to the "In Utero" album this full size cassette tape cover features vintage signatures from Kurt Cobain, David Grohl, Krist Novoselic & Pat Smear on different panels. Adding to the allure of this already incredible item is Cobain sketching the band's logo in felt tip marker. Known as an artist as well as musician, most art work remains behind lock & eye with the estate, but not this offering! Overall in fine condition & well preserved. It's worth noting this is the first authentic group signed "In-Utero" item we have not only handled, but ever seen in public auction. 1990's collectors take notice as this will be a centerpiece for years to come.
