In 1913, the Post Office began a new service called Parcel Post. For the first time anything, even live chickens, could go through the mail, as long as it was under 50 pounds. In 1914, Mrs. John Pierstroff bought 56 cents worth of postage for her 5-year-old daughter May and put her on a mail train. May made it to her grandmother's house in Lewiston, Idaho, 73 miles away. The Post Office immediately discouraged the practice, but several other children made it through the mail safely before the Post Office declared in 1920 that humans could no longer be posted.
On November 20, 1922 it happened again. This time the child was dead, mailed via Parcel Post to an undertaker in Albany, NY. The child was buried as Parcella Post because the parents were never discovered.
