Every European (and I guess non-Europeans as well) can vote what our next Euro design will be: https://surveys.ecb.europa.eu/10b/neweuro/
About ten different designs are available and about half of them feature birds instead of boring people.
I really like the bird designs as they symbolise freedom without borders. Hope one of them gets chosen in the end.
I wish they had different animals. Like birds for the 5€ (light), bears for the 200€ (heavy), and different animals in between.
And for the back famous art paintings.
