Analysis of information sources in references of the Wikipedia article "Euro banknotes" in English language version.
The ECB issues 8% of the total value of banknotes issued by the Eurosystem ... The other 92% of the euro banknotes are issued by the NCBs in proportion to their respective shares in the capital key of the ECB.
The Europa series has a revised map of Europe, including Malta and Cyprus. The tiny boxes near the bottom of the banknote show the Canary Islands and some overseas territories of France where the euro is also used. Very small islands are not shown on the banknotes because they cannot be accurately reproduced using high-volume offset printing.
