In 1956, the so-called European Community for Carbon and Steel, also coordinated the first emission of common design european stamps.
In order to spread the idea of european integration, a common design stamp was one way to distribute the idea throughout Europe.
For this first series, the 'construction' of Europe was the main theme.
In the design, the word EUROPE is shown as a newly constructed building.
The design was made by Frenchman Daniel Gonzague.
6 countries participated and in total 13 stamps were issued.
Belgium, West Germany (BRD), France, Italy, Luxemburg and the Netherlands.
Luxemburg mint is the most expensive part of this set, and has the key values.
