A US teenager has unearthed photos from Nirvana's first ever gig in 1987.
Maggie Poukkula, 19, posted a series of photos from the basement show to Twitter with the caption "Pictures of my dad and Kurt Cobain playing together back in the day."
Poukkula seemed unaware of the significance of the photos - until the fans swamped her feed.
