Pawngyang Furthon is not real. There is no convention, no badge, no guest list, no hotel block and no Mass Fursuit Games. Nobody is selling tickets, taking registrations or arranging travel, and nothing on this site is an offer of anything.
It is a comedy site. It pokes fun at the North Korean state's style - the vast spectacle, the bureaucratic language, the 105-storey hotel that never opened - and, affectionately, at the lovable chaos of fan conventions everywhere. The joke is on the regime and its theatre. It is never on the people who live under it.
The site is not affiliated with, endorsed by or connected to any real convention, government, airline, hotel, tour company or photographer. The fursuiters and cosplayers in the photographs are stock-photo subjects who have nothing to do with any of this and would probably be very confused by it.
