Rare photo from Hiroshima discovered

A rare photo has been discovered showing the mushroom cloud from the Hiroshima atomic bombing in two distinct parts, one above the other.

The black-and-white picture is believed to have been taken about half an hour after the bombing on 6 August, 1945.

"The existence of this shot was always known in history books, but this is the first time that the actual print has been discovered," a curator at the Hiroshima Peace Memorial Museum said.

"A shot showing the mushroom cloud split into two like this is very rare."

The ABC reports the photo was found among articles related to the atomic bombing now owned by

Honkawa Elementary School in Hiroshima city.

The best-known pictures of the aftermath of the bombing were taken from the air by the US military.

An American B-29 bomber named Enola Gay dropped an atomic bomb nicknamed Little Boy, that killed an estimated 140,000 in the final chapter of World War II.

Three days later another atomic bomb - Fat Man - was dropped on the city of Nagasaki, claiming the lives of another 70,000.
