A paper crane made by Sadako Sasaki, a young Japanese victim of the Hiroshima atomic bombing who died of leukemia a decade after the attack, was donated Saturday to a former training site for U.S. bombing crews during World War II.

Yuji Sasaki, 47, Sadako's nephew, donated her origami crane to Utah's Historic Wendover Airfield Museum ahead of the 72nd anniversary of the attack, which took place on Aug. 6, 1945.

Sadako became an icon for peace after folding more than a thousand of the origami cranes while being treated for leukemia 10 years after the bombing. She died at the age of 12 in 1955.
