Here’s a back-story for you.  We were in Taipei Airport and saw that the local Chunghwa Post branch was advertising these as maximum cards, but they had no stamps.  So within the boundaries of our limited Mandarin, we asked why they were called “Maximum Cards” when they plainly weren’t.  The postal person pulled out a sheaf of stamps and a chop and said “what date would you like on them?”  This was a novelty to us, so we just said “whatever works for you,” and this is the result.  The scan shows the two cards and the cardboard cover.  Unused.  Grade: 1
