There's a museum North of Kansas city called the Glore Pyschiatric Museum. it's an old insane asylum they've turned into a museum with all the old treatments they used to do, like human hamster wheel, a dunk tank, electroshock therapy, this coffin thing they'd put multiple people in for days, etc.
They also have projects from the patients there, like a wall full of cigarette packages they collected and two classic cars they rebuilt. Anyways one of the things they have is a collage of stuff they pulled out of a PICAs stomach, over 1400 things, mainly safety pins.
