Glue and Oil

During the Pacific War, two men plan a secret art exhibition...?! Kyoto, 1944. During the Pacific War, when people were unable to paint freely, Unohara Minoru and Tatsumi Masaki met. Though each of them carries their own wounds, the two plan a secret art exhibition... A passionate and free-flowing essay in "If I'm going to die someday, I'll sell my paintings first." Now, 80 years after the war, we, the only country in the world to have suffered an atomic bombing and the perpetrator of the invasion of Asia, once again look back on "that war."
