0 Euro - Zoo Duisburg

The 0 Euro souvenir program was launched in 2015 by Euro Souvenir, a private French venture, licensing the European Central Bank's visual idiom to produce legal-look collector pieces with no actual monetary standing. Oberthur Fiduciaire — one of the continent's principal security printers — produces the series, lending genuine banknote construction to what is essentially a licensed souvenir. The inclusion of a real security thread and hologram is a deliberate choice, not an affectation; it keeps the notes within the aesthetic register of circulating currency and prevents easy counterfeiting of the souvenirs themselves.

Duisburg Zoo, founded in 1934, is among the largest in Germany by animal count.
