On the face of it, five unused maximum cards issued in 1983, with enormous and beautiful stamps, and captions in Korean and English.  So far, so good.  However DPRK, along with 13 other nations, boycotted the 1984 Games in retailiation for a U.S.-led boycott of the previous 1980 Moscow Games.  One might think these cards would have been withdrawn from sale, but not so.   Please note, the postmark cancellations are all there but very difficult to read.  Overall, a most unusual set.  Grade: 1
