The cover art for Nirvana's classic 1991 album Nevermind has been banned from - the photo of a naked baby has been labelled as graphic content.
The picture of a swimming baby chasing a dollar bill underwater has become iconic, but the artwork was removed from the group's official fan page shortly after music bosses posted the image online to commemorate the record's 20th anniversary.
Executives at the social networking site claim the photo violates its terms of use clause.
The notice reads, "Facebook does not allow photos that attack an individual or group, or that contain nudity, drug use, violence or other violations of the Terms of Use."
But the boy who posed for the photograph 20 years ago, Spencer Elden, has no qualms about the naked snap being used on Facebook.
He says, "Quite a few people in the world have seen my penis. So that's kinda cool."
