It's to celebrate the twentieth anniversary of Nevermind's release fans are being called on to input.
The exhibition aims to "highlight the unique relationship the band enjoyed with their UK fans" and will feature professional photos, memorabilia and other treasured artifacts.
We're being called upon to add anything Nirvana related we have that we think should be a part of the exhibition by submitting a photo and description using a form on the website.
The exhibition will run for two weeks in September (exactly when TBC) at The Loading Bay Gallery in Brick Lane.
The super-special-deluxe edition of Nevermind - with CDs DVDs, B-sides, rarities etc - is out September 19.
