Here, I want to focus on the extreme postcards. "Extreme Postcard" is to stick a stamp coordinated with its theme on one side of the landscape postcard, and affix a postmark coordinated with tickets, movies or themes on its riding seam, thus forming an organic unity of tickets, movies and stamps.

Postcards can be divided into package and non-package. Generally, non-donated postcards have no collection value.
