Item #: SCP-4905
Object Class: Safe

Special Containment Procedures: SCP-4905 is to be kept in a locked room so no one can destroy it in any sort of way.

Description: SCP-4905 is a photo frame containing a black picture. When someone comes near the photo frame playing a Nirvana song, the black picture will become a picture of late Nirvana's singer Kurt Cobain. If someone comes near the photo frame with a Foo Fighters song (Nirvana's drummer band) the black picture will turn into a picture of Dave Grohl and Kurt Cobain smiling. There are many variations of the picture that might appear, one of them being of Kurt Cobain
smoking a cigarette.
Rarely, the photo frame will display a message saying "Thank you for this song".
