Three days after the beginning of the Russian invasion to Ukraine, I got a call from a Ukrainian-born friend. She said "you have to help us. We're going to protest in front of the Russian embassy and we need a poster". So I did.
Approach
Too many words are used all over. I decided none are needed, but just a cry against Putin. I used the colours of the Ukrainian flag.
Results
In the past two weeks, the poster is carried by demonstrators in all the protests against the war in Israel, in hundreds of copies.
