When Rick Elden agreed to let an image of his 4-month-old son be used for the album cover of 'Nevermind', he had never even heard of the band Nirvana.
So it must have been a shock to all involved when the album smashed expectations, became a landmark moment in music history and images of baby Spencer chasing a dollar bill on a fishing line were bounced all over the world.
Spencer Elden is now seventeen, and has recreated his famous image for an MTV documentary – though he's opted to cover up this time.
"It's kind of creepy that that many people have seen me naked," he claims. "I feel like I'm the world's biggest porn star."
Getting his kit off might be history, but funnily enough he's still chasing that dollar.
"Every five years or so, somebody's gonna call me up and ask me about Nevermind... and I'm probably gonna get some money from it."
You can hardly blame him for that, right?
