A paper crane made by Japanese girl Sadako Sasaki, an iconic victim of the 1945 U.S. atomic bombing of Hiroshima, has been donated to a Missouri library housing documents of late President Harry Truman, who authorized the attack.

The origami crane displayed at the Harry S. Truman Library and Museum, located in the hometown of the former president, is one of more than 1,000 cranes Sadako folded while in a hospital, praying for recovery after she was diagnosed with leukemia 10 years after the bomb was dropped on Hiroshima in the final stages of World War II. She died at the age of 12 in 1955.

At an event last week to mark the donation of the crane, seen as a symbol of peace, Sadako's brother, Masahiro Sasaki, said: "I donated the crane in the hope that emotional conflicts between Japan and the United States will come to an end. I have not felt hatred for the United States and I think Sadako felt the same."
