So I recently discovered there's an anarchist bookfair happening in Tartu, Estonia. So I made these icons as a way to contribute spreading the news. What do you think?
More info about the bookfair is here: https://riga-anarchist-bookfair.hotglue.me/
Great job. They all look good.
The bottom 2 look best to me. I think the circular one is more interesting, but the square might be more easily understood.
Good luck with the bookfair :)
