This is a very special postcard. Almost unique in the universe of postal correspondence, since it arrives via the world’s only underwater post office!

Located within the volcanic island country of Vanuatu, this unusual outpost combines our love of two things: diving and sending postcards to Wanda. We’ve provided evidence of the actual mailing since it’s got to be seen to be believed.

Also, this might be our most expensive postcard. Apparently waterproof postcards go for a premium.
