Describe the image that ends the story and explain its significance.

The story ends with a single wall standing amidst the rubble, like a tombstone. The wall continues to announce the date over and over--both the announcing of a date and this particular date are significant. That the wall stands alone announcing a date over and over reinforces the image of a tombstone, because tombstones generally prominently feature a date of death. The specific date mentioned--August 5th--is the day before the anniversary of the bombing of Hiroshima, reminding the reader of the "cause of death" in this story.
