Spencer Elden, the man who was photographed as a baby on the album cover for Nirvana's Nevermind, is suing the band alleging sexual exploitation.
The cover depicts Elden as a four-month-old in a swimming pool, grasping for a dollar bill that's being dangled in front of him on a fishing line.
Now 30, Elden says his parents never signed a release authorising the use of his image on the album.
He also alleges the nude image constitutes child cinema for adult viewingography.
"The images exposed Spencer's intimate body part and lasciviously displayed Spencer's genitals from the time he was an infant to the present day," legal papers filed in California claim.
Non-sexualised photos of infants are generally not considered child cinema for adult viewingography under US law.
