Poison convict's post-mortem art exhibit.

On a cold winter day in January 1948, a public health official walked into a bank and offered some people a potion that would cure dysentery, claiming that the epidemic was sweeping the neighborhood. 12 of the 16 people who tried it died soon thereafter from poisoning. A man named Sadamichi Hirasawa was convicted for the poisonings and handed a death sentence. In Japan, those sentenced to death can be terminated with almost no notice, but Hirasawa lived for 40 years until his hospital death in May of 1987. He lived until he was 95. 20 years after his death, Hirasawa's art work is being displayed on a busy Shibuya street, thanks to the efforts of his adopted son--who, interestingly enough, was adopted by the Hirasawa family mainly to advocate for the father's innocence.
