When the U.S. parcel post service was just starting out, some customers decided to test the limits on what could be mailed—which, for a time, included postmarking their children.
This is a staged photo from our @nationalpostalmuseum; in reality, children traveled with trusted postal workers (not in mailbags). The first child mailed in the U.S. was a boy in Ohio in 1913. It only cost 15 cents to send to him about a mile to his grandmother, but his parents did insure their child for $50.
While it was *technically* allowed for a couple years, the U.S. Postmaster General soon issued a "no humans" rule for the mail and the practice ended in 1915.
