surpass it. Postcard collecting's popularity can be attributed to

also used in both personal and business communication.The cards portray almost any subject that
one could imagine. This broad subject range comes as a result of the
social usage cards were designed for. Today postcards continue to be a
very popular form of souvenir for travelers and tourists.
