A Seattle, Washington teenager has uncovered a treasure trove of images from Nirvana's first gig.
Maggie Poukkula, 19, found the 1987 photos in one of her father's books and she has thrilled fans of the band by sharing them via Twitter.
Poukkula's dad, Tony, was a friend of Kurt Cobain's and the gig took place in his basement in Raymond, Washington.
The pre-Dave Grohl Nirvana line-up featured in the shots included Cobain, bassist Krist Novoselic and drummer Aaron Burckhard, along with Poukkula.
Maggie tells Rolling Stone, "My dad showed me them (photos) a while back, but he never mentioned what was going on in the photos. I found out because of all the articles (surrounding new documentary Montage of Heck).
"I had no idea that those were during Nirvana's first concert... I didn't realise it was such a historical thing. I thought they were just cool pictures of my dad and Kurt jamming together."
