A postcard is a thick of paper or thin cardboard intended for writing and mailing without an envelope. They are usually printed by a private company, individual or organization. Before, the post office was the only establishment allowed to print postcards. Good thing companies now are allowed to print postcards. I like postcards with photos where you can see different places or tourist spots in a certain country. Wish I could go travel to that places then send some postcards to my love ones so that they will know how nice the places are. I am wondering if it is easy to make postcards. They say that printing postcards is a tough job because designing them is not easy to make. They also say that online printing services saves time and money.
