It is a peace poster for the Peace Poster Exhibition to be held annually in Hiroshima. It is also a PR poster of a catalog published in commemoration of the 20th work of the appeals poster being held from 1983.

This lunch box is stored in Hiroshima Peace Memorial Museum.I think that a lunch box is a symbol of love and peace.I wish for a peaceful desire to resonate in the hearts of many people.

A lot of people attended the exhibition. I think that this poster has conveyed a message of peace to many people.
