1910s: Mailing a child
In the USA, the Post Office’s Parcel Post was introduced in 1913. Within weeks, a number of parents attempted to send their children by post.
In Ohio, Jesse and Mathilda Beagle posted their son James, eight months old, to his grandmother. The delivery cost 15c - cheaper than a rail ticket. Mr and Mrs Beagle insured James for $50.
In 1920, the Post Office elected to no longer deliver children.
