All hail the Eggman Empire! based on the "Sonic the Hedgehog" series, this set of six postcards was designed to imitate Dr. Eggman's databases, showing various locations and characters from the Sonic games. The stamps in this set include a large variety of characters on Eggman Empire themed backgrounds to match the overall packaging of the set. Also included as a hypothetical preorder bonus is a set of stamps based on the Wisps from "Sonic Colors".
