Mainz is the capital city of Rhineland-Palatinate and home to 218 000 people. It dates back to 13 BCE. The Roman's built a military fortress here as it was the northermost frontier of the empire and the provincial capital of Germania Superior. As part of the Holy Roman Empire in the 8 century, Mainz was the capital of the Electorate of Mainz and seat of the Archbishop-Elector of Mainz, the Primate of Germany.  Johannes Gutenberg was born in Mainz. He, of course, was the inventor of a moveable-type printing press. Gutenberg manufactured his first books here, including the Gutenberg Bible, in the early 1450s.  Mainz was heavily damaged during World War II. Allies carried out more than 30 air raids destroying about 80% of the city centre, including most of the historic buildings.  The card is an oversized, cartoonish picture of some of Essen's tourist attractions.
