Maxicard or Maximum card is a postcard with stamp(s) and postmark all of which have the same or closely related artworks. Stamp and postmark are on the picture side of the postcard.
In this blog, I'm going to show my maxicards, some of which I already sent to someone and no longer keep for myself.
Japan Post published official maxicards decades ago, but not recently. All maxicards on my blog are "self made" which means I purchased postcards and stamps separately, went to post office and have postmarks on them.
