📮✉️ A postcard is a small piece of cardstock or thick paper that is typically rectangular in shape and used for sending short messages through the mail. It usually features an image or photograph on one side, often depicting a scenic view or tourist attraction, while the other side is reserved for the recipient's address, postage stamp, and a brief message from the sender. Postcards are popular for sharing travel experiences, conveying greetings, or simply as a memento of a particular place or event. They offer a convenient and tangible way to connect with loved ones or communicate across distances, adding a personal touch to the act of sending and receiving mail.
