Congratulations to seismic-2 for a Deceptively Correct cover. Superdickery aside, there is no needs for a United Nations if Superman rules the entire planet. That complex would make for some premium housing.
As for the Peak of the Week and what this contest has taught the captain, comics are loaded with symbols. From the "S" shield, to the Bat logo, to Jughead's hat, simple basic items and pictures go a long way to invoking a character, a country, or an idea. Flags are a powerful tool to carry those idea within their symbolism.
