Alice cooper-from the inside.
this is a favourite of mine, i took a punt on it because of the awesome cover, it has a middle opening gatefold that reveals the inside of a mental asylum
, including a little door: "the quiet room" which when you open it, there's alice curled up on the floor, when you flip the back over, the track listing is on double doors that open to reveal more stuff, all this stuff hidden behind opening doors is on the inner sleeve.
it's amazing, like some macabre advent calender.
Those are the characters from the songs on the record.
AC has had several great album covers/extras including the paper panties from School's out. I have an original Billion Dollar Babies with the $1,000,000,000 bill as well as an original cardboard boxed Muscle of Love with the "Institute of Nude Wrestling" insert.
