An American teenager has unwittingly uncovered some never-before-seen photographs of Nirvana’s first ever gig and published them online, making her officially the coolest kid in the world right now.

19 year old Maggie Poukkula, from Seattle, Washington, found a photo strip dating from March 1987 in one of her father Tony’s books, and tweeted it to the delight of Nirvana fans worldwide. Her post contained the caption: “Pictures of my dad and Kurt Cobain playing together back in the day.”
