Snail Mail

How's this for slow? I was reading that the French postal service just delivered a postcard that was mailed September 29th 1910. It only took 96 years to get delivered to the recipient's daughter-in-law since the recipient had died in 1978.
Think about it, when the card (a picture of the Sémois valley in Belgium) was mailed the Titanic was not even completed, much less sunk. It was mailed four years before the First World War and 29 years before the start of the Second. The airplane was in its infancy and men walking on the moon was just a story by Jules Verne. Email? Forget it. There were telegrams, the telephone (if you didn't mind the neighbours and the operator listening in) and the Postal Service.
Gives a whole new dimension to the term "Snail-mail"
