The Hiroshima Peace Memorial Museum on Thursday put on display four paper cranes offered by U.S. President Barack Obama during his historic visit to the atomic-bombed city in May.

According to the museum, each of the Obama-handmade cranes is about 7 cm high and about 10 cm wide, and made of pink and blue paper with Japanese-style floral prints.

Obama visited the museum before attending an official service in the Peace Memorial Park on May 27. He gave one crane each to two local schoolchildren who welcomed him at the museum.
