Julien’s Auctions is a well-known auction house based in California, that has hosted many auctions surrounding music memorabilia. Next month, they’re hosting a “Music Icons” auction block.

One of Kurt Cobain’s most famous guitars is going into that auction. Specifically, the left-handed, blue, 1969 Fender Mustang, which he used in the music video for “Smells Like Teen Spirit”.

The guitar is expected to go for up to $800,000
“This is one of the most iconic guitars ever to come to the auction block, this is the blue Mustang Fender guitar, one of Kurt Cobain’s favorite guitars of all time,” the executive director of Julien’s Auctions said in a statement.

Kurt’s 1965 Dodge Dart will also be up for auction in May. Part of the proceeds from all the sales will go towards raising awareness on mental health disorders.
