I'm happy my poster was selected as one of the 100 best posters of 2016 (GER, A, CH).

When the UK decided to leave the EU I had a look at the Union Jack flag again.
I noticed the blue in the flag looks pretty close to blue of the EU flag.
I "erased" it and left the checker-pattern that symbolises emptiness, transparency or just the "alpha channel" in common design applications.
