This is a postcard from the Showa Station post office in Antarctica, featuring a pictorial postmark. It combines the stamp, postcard, and the design of the pictorial postmark. The back is unused, so you can send it again by attaching a new stamp. The Showa Station postmark is the southernmost pictorial postmark. To get the pictorial postmark, you need to send it before the ship departs, and it takes over six months for delivery after it returns. I made this maximum card half for fun, but I'm selling it because I've stopped collecting them.
