Canisters of the Dead at Oregon State Hospital... For decades, thousands of nondescript copper canisters sat on a shelf in the basement of Oregon State Hospital. That was until photographer David Maisel got a chance to take a look at them. It turns out that each canister held the remains of a former psychiatric patient. Talk about a morbid discovery. Today, the canisters have been respectfully removed and placed in a memorial for the forgotten dead.
