In Joplin’s first few years in the 20th Century, its ever growing population sent an ever growing amount of mail. A newspaper sketch decided to illustrate that amount of mail by showing how high it would stack in a single column. As noted, it would go well over the roof of the Keystone Hotel, the tallest building in town at that time (until eclipsed by the Connor Hotel).
