This is more of a group of 12 and less an integrated set, because eight of the cards are numbered in sequence while the remaining four look a little different on the back.  But it is as we received it from the official distributor.  Anyway, all of the unused cards have pre-printed postage and are captioned in Korean only.  The scan shows the  paper cover (lower right) and three of the 12 cards.  Grade: 1
