Here we have one of my absolute favourites.
At the time when postcards were at their height, most overseas mail was coming in by ship. Vessels like RMS Titanic carried mail from England to North America and vice-versa, making it possible for people to keep in touch with relatives far away during a time before telephones and internet. Of course, if the vessel containing your postcard went down… you get the idea.
Give a toast to the Royal Mail ships of old and the planes of today! And, perhaps, consider getting into the habit of sending postcards to your loved ones, because it’s still a joy to get something in the mail that isn’t a bill.
