Prior to 1920, it was possible to send children through the US Postal service. However, there were certain conditions that needed to be met. Firstly, the children had to weigh less than 50 pounds, and stamps were attached to their clothing as a form of payment. Surprisingly, it was often more cost-effective for individuals to send their children via mail rather than opting for train transportation. Interestingly, during the journey, the children would travel on a train, specifically in the mail car, where they were supervised and provided with nourishment by mail clerks. One remarkable example of this unconventional practice involved a distance of over 700 miles, from Florida to Virginia, covered with a mere 15 cents worth of stamps.
