The front cover for the Nirvana album Nevermind is surely one of the most well known album covers of all time. It's the one with a baby underwater in a swimming pool, swimming towards a dollar bill.
That cute little baby is now 20, as is the album. Spencer Elden was four months old when he was snapped for the front cover. He's a big fan of Nirvana's music, and often gets introduced to people as 'the Nirvana baby.' Sadly, he didn't get paid to do it, as it was a favour from his parents to their photographer friend.
The only downside is, everyone has seen his bits..
Anywhere, here's an interview with Spencer.
