Postcard ES-84973

Is there any other postcard other than this card that travelled further from its source to its destination? If so, I would be curious. Antipodes on the earth are just a bit more than 20,000 km apart, so this postcard was practically sent to the opposite side of the planet from its source.

Wow, I hadn't even thought about that. It must be one of the furtherest ones sent. How cool.
