A total of 4,208 artworks were submitted by children from 123 cities in 21 countries around the world, all members of Mayors for Peace. Of these, 20 were selected as prize-wi'nning works.
  These works, which convey children's messages of peace, have been actively exhibited during conferences related to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and the Treaty on the Prohibition of Nuclear Weapons (TPNW) and are planned to be showcased at the United Nations Headquarters in New York.
