We found this Eurographic (Credit to EUball) that shows European Union map: the member states, the candidates and the potentional candidate (those who not applied yet for membership). Also, we can observe the founders of European Union, the countries that are in the Eurozone and the countries which are not in EU but have euro.
Which are the founders of European Union?
Which candidate will be the next who will take part of the European Union?
What do you think about Eurozone?
