A post card has come here all the way from far away.

People who receive this post card would think, “it has come here all the way from far away. People who send this post card would talk to the card in their mind, “Take care! Have a good trip.”

That is how the post card works.

In either case, you would cherish this post card.

このポスカードが送られてきた人にとっては「はるばるやって来たのだな」と思ってもらえて、

このポストカードを送る人にとっては「いってらっしゃい」と思ってもらえる。

そんなポストカード。

​いずれにしても、ポストカードを愛おしく思える。
